How We Selected These Hidden Gems

This shortlist uses records marked "Very confident" in the legacy directory, listed with no entry fee, and containing a longer description. Records are ordered by description length and highlight count. Those legacy fields are not independent verification of access, water quality or present-day fees. We show up to ten candidates, not a ranking of safety or seclusion.

  • Confirm permission and any permit or reservation requirements
  • Check the actual route and parking location with the land manager
  • Read current closure and water-quality notices
  • Keep an alternative plan if the site is closed or crowded
Pro Tip
Download offline maps and save each stop before you drive - signal can vanish when you're closest to the good stuff.

Best Seasons and Timing in California

Check current conditions and local advisories for the exact waterbody before travelling. Do not assume water is suitable simply because a day or two has passed since rain, or because it looks clear. Follow posted closures and the land manager's guidance instead of a fixed waiting period. See the CDC's natural-water swimming guidance for advisory checks, especially after heavy rain.

Access, Parking, and Navigation

Bring downloaded maps and avoid blocking gates or driveways on narrow rural roads. Many of these sites use small turnouts that fill early on weekends. If a spot looks crowded, please move on rather than creating new social trails or shoulder parking. Pack light for short scrambles and expect wet rocks; shoes with traction make a big difference.

Respect the Place
If a lot is full, pick the next stop. Avoid creating social trails or parking in vegetation - these spots stay hidden by staying healthy.

Pack Like a Local

  • Water shoes with grip; lightweight towel and dry bag
  • Sun protection and layers - shade can be limited by mid-day
  • Plenty of drinking water and salty snacks; trash bag to pack out
  • Optional: trekking poles for steep, dusty, or slabby approaches

Before You Go

Please respect these natural areas by following Leave No Trace principles. Check local conditions, respect private property, and always prioritize safety when visiting remote swimming holes. If conditions look unsafe, choose a calmer alternative - these places will be here another day.

Auburn American River Swimming Spots

Sacramento, California
River

About Auburn American River Swimming Spots

Tucked into the rugged canyon country of the Sierra Nevada foothills, the American River swimming spots near Auburn offer something that chlorinated pools simply cannot replicate: the raw, elemental pleasure of cold, snowmelt-fed water rushing over granite bedrock beneath an open California sky. Within the Auburn State Recreation Area, the North Fork and Middle Fork of the American River carve their way through dramatic gorges, creating a network of unofficial swimming holes that locals have been quietly treasuring for generations.

The Setting: Granite, Gold, and Wild Water

You'll arrive to a landscape that feels ancient and alive at the same time. Massive granite formations rise from the riverbanks, their surfaces worn smooth by centuries of water and weather — perfect for sunning yourself between dips or setting up a camera to capture the scene. Sandy shores and rocky outcroppings line the water's edge, while oaks, pines, and a tangle of vibrant riparian flora crowd the canyon walls above. Keep your eyes open: river otters, hawks, and a surprising variety of wildlife call this corridor home. The entire area sits on land steeped in Gold Rush history, and it's easy to let your imagination wander as you wade through the same waters that once drew thousands of fortune-seekers west in the 1850s. Some say the legends of that era still linger in these canyons — though whether that adds to the atmosphere or gives you a slight chill is entirely up to you.

The Swimming Experience

The character of the river changes dramatically with the seasons, and that variability is part of the appeal. In late spring, snowmelt from the Sierra Nevada sends swift, energetic currents tumbling through the gorge — exhilarating for confident swimmers who respect moving water, but demanding genuine caution. By summer and into early fall, the river mellows into its most welcoming mood: clearer, calmer pools collect behind boulders and along sandy bends, the water cool and bracingly refreshing against the heat of a foothill afternoon. Clarity is typically good, with the characteristic blue-green tint of granite-filtered mountain water. Note that these are unofficial swimming areas with no designated lifeguards or safety staff on site, so swimming here is entirely at your own discretion and risk.

Planning Your Visit

Getting to the river requires a moderate effort. Trails leading down into the canyon tend to be steep and rocky, so sturdy footwear and a baseline level of fitness will serve you well. Bring plenty of water, sun protection, and snacks — facilities at the swimming spots are not confirmed, so plan to be self-sufficient. The good news is that entry is free. If you want to extend your stay, several camping options exist along the river, making it easy to spend a full weekend exploring different stretches of the canyon. Highway 49 provides the main access corridor into the area. Auburn itself sits roughly 35 miles northeast of Sacramento and about 100 miles southwest of Reno, Nevada, making these swimming holes a genuinely accessible escape from two major metro areas. Whether you're driving up from Sacramento for a day trip or passing through on a longer Sierra Nevada adventure, the American River near Auburn rewards anyone willing to make the hike down.

Nearby Swimming Holes and Trip Planning

If you are planning a longer day in the area, it pays to line up a few options. Within reach you will also find Yuba River Swimming Holes And Recreation Area (about 26 miles away), Truckee-Tahoe Sierra Swimming Spots (about 48 miles away), and Chico Region Swimming Holes (about 71 miles away). To plan further, browse more California swimming holes, compare other river swimming holes, or read about lesser-known spots in California.

Cool, clear waters fed by Sierra Nevada snowmelt
Granite rock formations and sandy shores
Rich Gold Rush history surrounding the area
Abundant wildlife and vibrant flora
Water Body: American River
Best Time: Spring for dynamic swimming conditions due to snowmelt; summer and early fall for calm waters and warm weather; winter for peaceful hikes and scenic views.

Buckeye-Travertine Hot Springs and Creek Destinations

Carson City (NV), California
Hot Springs

About Buckeye and Travertine Hot Springs

Tucked into the high desert landscape of the Eastern Sierra near Bridgeport, California, Buckeye and Travertine Hot Springs represent two of the most rewarding — and wildly different — geothermal soaking experiences in Toiyabe National Forest. Neither destination is developed or officially managed, which means you get something increasingly rare in the American West: a genuinely wild soak, where the smell of sulfur mingles with sage and pine, and the backdrop is pure Sierra Nevada grandeur.

The Setting and Landscape

Buckeye Hot Springs clings to a hillside above Buckeye Creek, where geothermally heated water cascades down a terraced rock face into naturally formed pools at the water's edge. The creek rushes below, cold and fast with snowmelt for much of the season, and the contrast between icy creek water and the steaming mineral pools is part of the magic. Cottonwoods and willows frame the creek corridor while open sagebrush slopes rise on either side, framing views toward the surrounding peaks.

Travertine Hot Springs, by contrast, feels almost otherworldly. Brilliant white travertine formations — built up over centuries by mineral-laden geothermal water — create a lunar-like landscape of snow-white pools perched above the valley floor. From here, panoramic views of the Sierra Nevada and the Bridgeport Valley stretch out in every direction, especially vivid at sunrise and golden hour. The two sites share a region but could not feel more different in character.

Soaking and Water Experience

Both destinations are hot springs rather than traditional swimming holes — the experience here is therapeutic soaking rather than laps or diving. The mineral-rich waters are believed to carry restorative properties, and even a short soak leaves skin feeling silky and muscles noticeably looser. Temperatures vary by pool and season, and savvy visitors mix their soaking with a wade into Buckeye Creek to cool off between sessions. The pools are naturally formed and shallow enough for comfortable lounging, and the geothermal flow means the water is continuously renewed.

Because these are unofficial sites, there are no lifeguards, no designated swimming areas, and conditions can change. Come prepared to read the environment on your own terms.

Plan Your Visit

The best time to make the trip is between May and October, when the roads are passable and the landscape is at its most alive — wildflowers in spring, crisp mountain air in fall. Getting to Travertine requires navigating an unpaved road, and winter access to both areas may demand a 4WD vehicle. Buckeye benefits from a nearby National Forest campground with picnic tables and toilets, making it an ideal basecamp for a night or two under the stars. Travertine has no facilities, so bring everything you need. Both springs are free to visit. The closest full-service town is Bridgeport, California, where you can fuel up and grab supplies before heading out. Carson City, Nevada, lies to the north and offers additional lodging and dining options for those traveling the greater region.

Nearby Swimming Holes and Trip Planning

If you are planning a longer day in the area, it pays to line up a few options. Within reach you will also find Yosemite National Park Swimming Spots (about 41 miles away), and Gods Bath (about 49 miles away). To plan further, browse more California swimming holes, compare other hot springs swimming holes, or read about natural hot springs.

What Makes It Special:

Geothermal hot springs
Striking Sierra Nevada views
Camping facilities at Buckeye
Therapeutic mineral-rich waters
Water Body: Buckeye Creek/Hot Springs
Best Time: The best time to visit is between late spring (May) and early fall (October) when the weather is mild, roads are accessible, and the surrounding landscape is at its most vibrant. Winter visits can offer unique views but may require 4WD access.

Willow Creek Swimming Spots in Shasta-Trinity National Forest

Redding, California
Varies-see below

About the Willow Creek Swimming Spots in Shasta-Trinity National Forest

Tucked deep within the ancient folds of Shasta-Trinity National Forest, the swimming spots along the North Fork Trinity River near Willow Creek are the kind of places that make you feel like you've discovered something the rest of the world forgot. The water runs crystalline — the sort of clarity that lets you count pebbles ten feet below the surface — and its coolness hits your skin like a quiet shock on a blazing summer afternoon. These are informal, unhurried places, beloved by locals and rewarding to anyone willing to earn them on foot.

The Setting: Rugged Canyons and Ancient Stone

The landscape here is elemental. Ancient rock formations, shaped over millennia by the relentless carving of the North Fork Trinity River, rise in rugged bluffs above pools that glow with that deep blue-green color unique to undisturbed mountain water. The surrounding forest is dense and fragrant — pine, fir, and the rustling presence of canyon oak — while the river corridor opens up the sky just enough to let light pour in and dance across the surface. In spring, wildflowers crowd the trail margins and everything glows with fresh green intensity. By autumn, the same hills burn with amber and rust. Even winter has its pull here, offering stark, quiet beauty for those seeking solitude over a swim.

The Swim: Cool, Clear, and Unhurried

Getting to the water requires a quarter-mile hike along a narrow, uneven path — nothing technical, but enough to reward you with a sense of arrival. Once you reach the river, you'll find multiple informal spots to choose from, each with its own character depending on season and flow conditions. Water depth, current, and clarity shift throughout the year, so summer visits generally offer the calmest, most swimmable conditions. The pools are cool even in July, a bracing antidote to inland California heat. Tubing is a popular way to experience the gentler stretches of the river, letting the current do the work while canyon walls drift past overhead. There are no lifeguards present at these unofficial sites, so swimmers should assess conditions carefully and exercise sound judgment, especially with children.

Practical Details and Local Character

Access to these spots carries no entrance fee, and the area's informal nature is a big part of its charm — no crowds, no concession stands, just river rock, cold water, and the sound of moving current. Facilities vary by specific location along the route, so come self-sufficient: bring water, snacks, sun protection, and shoes with grip for the trail. Camping is available at several National Forest campgrounds along the corridor, making this an ideal base for a multi-day escape into the wild Trinity country. History adds another dimension to a visit here: the area sits in proximity to Helena, a former gold rush ghost town that whispers of a more turbulent California past.

Plan Your Visit: The nearest services and fuel can be found in Willow Creek to the west or Redding to the east, both of which offer lodging, dining, and supplies. The small community of Helena sits closest to the swimming corridor itself. Highway 299 serves as your main artery through this stretch of Northern California, connecting the communities and providing access points into the forest. Come in summer for the best swimming, but don't overlook the quieter seasons — each one offers something worth the drive.

What Makes It Special:

Clear pools
Rugged rocky bluffs
Cool water temperatures
Historical nearby ghost town
Water Body: Varies-See Below
Best Time: Spring for wildflowers and greenery, summer for swimming, autumn for colorful foliage, and winter for solitude and stark beauty.

Navarro River Swimming Spots

Mendocino, California
River

About Navarro River Swimming Spots

Tucked into the forested heart of Mendocino County, the Navarro River swimming spots offer one of California's most quietly rewarding freshwater escapes. This is the kind of place you almost feel lucky to find — an unofficial, unhurried stretch of cool, clear river where the redwoods lean over the water and the outside world seems very far away. Locals have known about it for generations, and savvy visitors who venture off the main road are richly rewarded.

The Setting: Redwoods, River, and Solitude

The Navarro River winds through a cathedral landscape of towering coast redwoods, their massive trunks draped in emerald moss and their canopy filtering the coastal light into something soft and golden. The air carries the mingled scents of damp earth, fern, and fresh water — the unmistakable perfume of a healthy old-growth corridor. At the swimming hole near milepost 3.00 and 3.01, you'll descend a gentle slope between two sentinel redwoods, and the river opens before you in a sweep of gravel bar, polished stones, and moving water. The surrounding terrain is lush and vibrant from late spring through early fall, when the Navarro runs at its most inviting.

The Water: Cool, Clear, and Refreshing

The Navarro runs cold and clear in the way that only a river fed by forested hills can. You'll feel the chill the moment you wade in — a bracing, exhilarating cold that makes a hot summer afternoon feel like a gift. The water is clean and freshwater all the way, with a natural, unspoiled character that developed swimming facilities rarely match. Visibility into the river bottom is excellent in the calmer pools, where you can watch the current ripple over smooth river stones. This is a place to float, splash, and simply be in the water — not a destination for structured swimming, but for the kind of spontaneous, joyful immersion that reminds you why natural places matter. Children and adults alike will find the accessible entry and gentle conditions approachable, though water levels and currents can vary seasonally.

Practical Information: What to Know Before You Go

Access to the swimming hole near milepost 3.00/3.01 is via a discreet roadside pullout, making it easy to reach without a long hike. The short walk down to the water involves a gentle slope, but the terrain can be slippery — sturdy, closed-toe shoes are strongly recommended. There are no developed facilities on site: no restrooms, no changing areas, and no lifeguards or safety staff present. Come prepared with everything you need, including water, snacks, and a way to pack out any trash. The swimming spots are unofficial, so visit with a leave-no-trace mindset and respect the natural environment. The best window for a visit runs from May through October, when temperatures are warmer and water levels are stable.

Plan Your Visit: The Navarro River swimming spots sit within easy reach of several Mendocino County communities. The charming coastal town of Mendocino is a short drive to the west, offering galleries, restaurants, and lodging. Fort Bragg lies further up the coast and provides additional dining and accommodation options. Inland, the small communities of Philo and Navarro put you right in the heart of Anderson Valley wine country. Overnight options include camping at nearby Navarro Redwoods State Park and Hendy Woods State Park, both of which place you directly in the redwood forest and close to the river.

What Makes It Special:

Clear, cool water perfect for swimming
Surrounded by towering redwoods
Accessible roadside location
Rich local history and wildlife
Water Body: Navarro River
Best Time: The ideal time to visit is between late spring and early fall (May through October) when temperatures are warmer, water levels are stable, and the surrounding landscape is lush and vibrant.

Lake Arrowhead and Deep Creek Swimming Spots

San Bernadrino, California
Creek/ Hot Springs

About Deep Creek Hot Springs in San Bernardino National Forest

Tucked into a rugged granite canyon within the San Bernardino National Forest, Deep Creek is one of Southern California's most rewarding natural swimming destinations. Here, a cold, clear mountain creek tumbles over ancient rock and pools beside natural hot springs — a combination that feels almost impossible until you're standing in the middle of it, one foot in ice-cold current and the other soaking in geothermal warmth. This is a place that earns its magic, and the 1.75-mile hike in only makes the arrival sweeter.

The Setting: Granite, Water, and Wild Sky

Deep Creek carves through a dramatic canyon shaped by centuries of flowing water, leaving behind smooth granite formations that rise from the creek bed like sculpture. The rock is warm to the touch on summer afternoons, perfect for stretching out between dips. In late spring, wildflowers push through the sandy canyon soil, adding splashes of color against the pale stone. Keep your eyes open — this corridor of water draws native wildlife, and sightings of birds, lizards, and other canyon inhabitants are common. In autumn, the surrounding hillsides shift into golds and russets, making the hike itself as rewarding as the destination.

The Water: Creek Swimming and Natural Hot Springs

Deep Creek's water is clear, fed by mountain snowmelt and filtered through granite. The creek runs cool and refreshing during the swimming season, offering a bracing contrast to the warm desert air. But the real draw is the natural hot springs that emerge along the creek's edge, creating shallow soaking pools where the mineral-rich water hovers at a soothing temperature year-round. You can move between the cold creek current and the hot spring pools, letting your body adjust and relax in alternating temperatures — a hydrotherapy experience that needs no spa to deliver. The best swimming season runs from April through August, when water temperatures and air temperatures align for comfortable, extended time in the water.

Planning Your Visit: What to Know Before You Go

This is an unofficial, unsanctioned site managed within the United States Forest Service's jurisdiction, which means there are no facilities on-site — no restrooms, no lifeguards, and no services of any kind. Come fully prepared: bring plenty of water, sun protection, snacks, and a first aid kit. Wear sturdy footwear appropriate for uneven terrain and some elevation change along the 1.75-mile trail. The United States Forest Service does not permit camping within one mile of the hot springs, but a privately operated camping and parking facility that opened in 2020 sits approximately 1.75 miles from the springs and serves as the practical staging point for most visitors. There is no entrance fee to access Deep Creek itself.

Plan Your Visit: Deep Creek is most easily accessed from the communities of Hesperia and Lake Arrowhead, with the city of San Bernardino serving as the nearest major hub for fuel, groceries, and lodging. Whether you're driving up from the Inland Empire or passing through on a larger High Desert road trip, this stretch of canyon water is worth carving out a full day to experience properly.

What Makes It Special:

Natural hot springs for relaxation
Striking granite formations
Clear waters
Seasonal wildflower blooms
Water Body: Deep Creek
Best Time: The best time to visit Deep Creek is during late spring and summer (April to August) when the weather is warm and the water temperature is ideal for swimming. Autumn (September to October) offers cooler temperatures and dramatic foliage, perfect for hiking and photography.

Humboldt Redwoods Swimming Holes

Eureka, California
River

About Humboldt Redwoods Swimming Holes

There are few places in the American West where a swim feels as genuinely otherworldly as it does along the Eel River inside Humboldt Redwoods State Park. The trees alone would be enough — coast redwoods so tall they seem to belong to another era — but the river sliding through their roots adds something cool, unhurried, and alive. This is swimming in the shadow of giants, and it earns that description every time.

The Setting: Ancient Forest Meets Moving Water

The swimming holes here sit within the world's largest remaining old-growth coastal redwood forest, where the Eel River and its South Fork cut through groves that have stood for centuries. Sunlight filters down in long shafts between the trunks, dappling the water's surface in patterns that shift with the breeze overhead. The air carries that distinctive redwood smell — damp bark, forest floor, cold water — and the riverbanks are quiet in the way that only deep forests can be. Along the shore, you'll find smooth stones, a canopy that keeps the summer heat at bay, and the gentle sound of current moving over rocks. One of the more unusual features is a concrete jetty that juts into the river, offering adventurous swimmers a spot for careful jumps into the water below.

The Water Experience

The Eel River runs clear and refreshing through the warmer months, and its natural pools invite both swimmers and tubers who want to let the current do the work. The water is cold — this is a snowmelt-fed Northern California river — and that chill is half the pleasure after a warm afternoon walk among the redwoods. By late spring, when flows ease and temperatures climb, the conditions settle into what most visitors would call ideal: manageable currents, good visibility into the riverbed, and enough depth in the pools to swim freely. Keep in mind this is a semi-official swimming area with no lifeguards on duty, so awareness of conditions and your own comfort in moving water matters.

Planning Your Visit

Access is straightforward and suitable for most visitors. You'll drive through the historic mill town of Scotia and follow a short path down to the river — the kind of easy approach that makes this a realistic outing for families and casual adventurers alike. All facilities are available along the Avenue of the Giants corridor and at the State Park campgrounds. Swimming is free, and if you're planning to stay overnight, three campgrounds — Hidden Springs, Burlington, and Albee Creek — are available within the park. Reservations are strongly recommended, especially in summer. The best window for a visit runs from May through September, with summer mornings and evenings offering cooler air and lighter crowds. The nearby Avenue of the Giants makes this an easy add-on to a longer road trip through the region.

Plan Your Visit: The swimming holes are most easily reached from the towns of Scotia, Miranda, Weott, and Redcrest along the Avenue of the Giants corridor. Eureka to the north and Garberville to the south serve as the main regional hubs for fuel, lodging, and supplies before you head into the park.

What Makes It Special:

Towering redwoods surrounding the swimming hole
Clear, refreshing water of the Eel River
Unique concrete jetty for careful jumps
Camping at state park campgrounds
Water Body: Eel River, South Fork Eel River
Best Time: The best time to visit is late spring through early fall (May to September) when water temperatures are ideal for swimming and currents are gentler. Summer mornings and evenings offer cooler air and fewer crowds.

Hatchet Creek

Redding, California
Falls

About Hatchet Creek Falls

Tucked away in the rugged landscape of Shasta County, California, Hatchet Creek Falls is the kind of place that rewards the curious and the adventurous. This unofficial, undeveloped swimming hole sits along the clear, cold waters of Hatchet Creek, surrounded by dense vegetation, moss-covered rock formations, and the kind of quiet that reminds you how far you are from everyday life. There are no signs pointing you here, no parking attendants, no amenities — just wild water, dappled sunlight, and the sound of a waterfall doing what it has always done.

The Setting and Landscape

Getting to Hatchet Creek Falls requires a short but moderately challenging hike through terrain that doesn't come with marked trails or handrails. You'll push through dense brush, pick your way across uneven ground, and then suddenly, the creek opens up before you. The water runs clear over natural rock formations, carving pools that glitter in the filtered light breaking through the tree canopy overhead. In spring, the surrounding hillsides are electric green, fed by snowmelt and seasonal rains. By summer, the foliage deepens and the air smells of warm earth and pine. In fall, the crowds thin further and the leaves shift to amber and gold, making it a striking destination for photographers and those who simply want stillness. The untouched character of this place is its greatest asset — it feels genuinely discovered rather than designed.

Swimming and Cliff Jumping

The creek's clear water and natural rock ledges make Hatchet Creek Falls a favorite among locals who know where to look. Swimmers can wade into the pools beneath the falls, where the water is refreshingly cold even on the hottest summer afternoons. The natural rock formations rise at various heights above the water, offering jumping spots for those with the nerve and the judgment to use them safely. There are no lifeguards or safety staff on site — this is a place that asks you to know your own abilities and respect the environment. Children and less experienced swimmers should take extra care, and everyone should scout jump points carefully before leaping. The reward for those who are prepared is a swimming experience that feels genuinely wild and exhilarating.

Plan Your Visit

Hatchet Creek Falls is an unofficial site with no facilities — no restrooms, no picnic tables, no trash cans. Pack in everything you need and pack out everything you bring. There is no entry fee confirmed for this location. The best time to visit is summer, when temperatures are warmest and swimming conditions are at their peak, though spring and fall each offer their own rewards. Winter access can be difficult and is best avoided. The falls sit within reach of both Redding and Burney, California, making either town a practical base for your trip. Burney in particular puts you close to some of the most spectacular natural attractions in Northern California, including Burney Falls and Lassen Volcanic National Park. Plan your day around an early arrival to secure a good spot and give yourself time to explore before the light fades.

What Makes It Special:

Clear water perfect for swimming
Opportunities for jumping from rocky ledges
Untouched wilderness and serene surroundings
Ideal for photography and wildlife spotting
Water Body: Hatchet Creek
Best Time: Summer for warm temperatures and swimming, spring for vibrant greenery, fall for quieter visits and changing foliage. Avoid winter due to accessibility challenges.

Forest Glen

Eureka, California
River

About the Forest Glen Swimming Hole

Tucked into the heart of Shasta-Trinity National Forest, the swimming hole at Forest Glen Campground is one of Northern California's quiet treasures. Here, the South Fork of the Trinity River winds through a landscape of towering conifers, mossy boulders, and fern-draped banks — a world apart from the noise of everyday life. Whether you're a weekend camper or a day-tripper chasing cool water on a hot summer afternoon, Forest Glen delivers an experience that feels genuinely wild without demanding anything extreme of you.

The Setting and Landscape

The South Fork of the Trinity River runs with a clarity that stops you in your tracks. Standing on the bank, you'll look down into water that shifts from pale jade to deep emerald depending on the light and the depth. The campground hugs the river's edge, so the transition from camp chair to cool water takes all of thirty seconds. Ancient Douglas firs and pines press in from all sides, casting dappled shade across the rocky shoreline, while the scent of pine resin and river mist mingles in the warm summer air. In spring, wildflowers erupt across the surrounding hillsides in waves of color. By autumn, the canyon walls ignite with gold and amber, making this one of those rare spots that earns a return visit in every season.

Swimming and Snorkeling

The river here is approachable enough for families but rewarding enough for adventurers. You'll find pools of varying depth tucked between smooth granite boulders — shallow enough near the edges for kids to wade and splash, deeper toward the center for those who want to fully submerge. The water is cold and bracingly clear, the kind of mountain river water that makes your skin tingle and your spirits lift immediately. Snorkelers will appreciate the visibility, which reveals the stony riverbed and whatever small creatures make their home in the current. Water shoes are strongly recommended: the river bottom is rocky and uneven, and the right footwear lets you explore freely without watching every step. Note that this is an unofficial swimming spot with no lifeguards on duty, so swimmers should exercise caution, especially with children and during higher spring flows.

Plan Your Visit

Forest Glen Campground sits within Shasta-Trinity National Forest, and camping is available directly on site — meaning you can wake up twenty feet from the water and spend the whole day in and out of the river. Facilities are available at the campground, and there is currently no fee to visit, making this an exceptional value for families and budget-conscious travelers. Summer months from June through August offer the warmest temperatures and the most stable water levels, making them the prime window for swimming and snorkeling. The nearest towns include Eureka and Fortuna to the west and Redding to the east, all of which offer fuel, groceries, and lodging if you prefer a base camp with more amenities. However you arrive, Forest Glen rewards those who make the effort with one of the Trinity region's most unspoiled riverside escapes.

What Makes It Special:

Clear emerald waters
Set within Shasta-Trinity National Forest
Perfect for swimming and snorkeling
Accessible from nearby towns
Water Body: South Fork of the Trinity River
Best Time: Summer months (June-August) for warm temperatures and stable water levels; Spring (April-May) for vibrant wildflowers; Autumn (September-November) for striking foliage.

Gods Bath

Stockton, California
River

About God's Bath on the Clavey River

Tucked deep within the Stanislaus National Forest, God's Bath is the kind of place that feels like a reward. Carved over millennia by the Clavey River, this natural plunge pool sits cradled by smooth, sun-warmed granite, its water so clear you can count every pebble on the bottom. This is an unofficial swimming hole — no signs will guide you in, no lifeguards will watch over you — but for those willing to work for it, the payoff is a stretch of unspoiled Sierra Nevada wilderness that feels entirely your own.

The Setting and Landscape

The Clavey River cuts through a rugged, remote canyon, and God's Bath captures everything that makes this corner of California extraordinary. Granite formations rise around the pool in pale, sculpted curves, polished smooth by centuries of rushing water. Ponderosa pines and oaks lean over the canyon walls, filtering the sunlight into shifting patterns on the river's surface. In summer, the air smells of warm stone and pine resin. In autumn, the surrounding foliage ignites in gold and amber, turning a swim here into something close to a painting. Wildlife is a genuine presence — keep your eyes open for birds, deer, and the occasional river creature going about its day along the banks.

What Swimming Is Like

The water at God's Bath is cool and crystalline, fed by Sierra snowmelt and shaded by canyon walls that keep it refreshing even during the hottest weeks of summer. The natural plunge pool offers depth enough for jumping from the surrounding granite ledges, and the clarity of the water makes it feel almost impossibly clean. June through August delivers the most comfortable conditions for swimming, when flows have calmed from the energy of spring runoff and the granite bakes warm enough to dry you off between dips. Spring brings a different character entirely — the river runs with more force and drama, and the canyon echoes with the sound of moving water. Come in autumn and you may have the whole place to yourself.

Plan Your Visit

Getting to God's Bath requires some effort. The terrain is moderate to challenging, involving rock scrambling and uneven ground, and the site's remote location means you should bring GPS coordinates rather than relying on posted signage. There are no facilities of any kind on site — no restrooms, no trash cans, no parking infrastructure — so pack in everything you need and pack out everything you bring. There is no camping at the site itself. The swimming hole carries no entrance fee, but the real cost is the preparation it demands: sturdy footwear, plenty of water, sun protection, and a solid plan for navigation. The nearest towns for supplies, fuel, and lodging are Stockton to the west and Sonora to the south. Sonora in particular makes an excellent base camp, offering restaurants, gear shops, and the warm, unhurried character of a Gold Rush-era foothill town. From either direction, the drive into Stanislaus National Forest is itself a scenic experience worth savoring.

Granite rock formations

Aquatic Park

San Francisco, California
Saltwater beach / bay cove

Aquatic Park: saltwater swimming in San Francisco

Aquatic Park Cove is on San Francisco Bay in San Francisco Maritime National Historical Park. This is an open-water beach, not a freshwater pool. The National Park Service lists swimming among the cove's activities.

Conditions and facilities

No lifeguards are on duty. NPS warns about marine animals and boat traffic. Public showers and changing rooms are unavailable; restrooms are at the Maritime Museum. Do not assume access to private swimming-club facilities.

Getting to the beach

The beach adjoins the paved Aquatic Park Promenade, but reaching the water requires crossing sand. An accessible promenade does not establish accessible water entry or suitable swimming conditions.

Fees and planning

NPS lists no swimming activity fee. Its current fees page says no park entrance pass is required. Check current notices before visiting; this listing does not establish today's water quality, temperature or closure status.
