Wyoming Waterfall Swimming Holes

TL;DR: If you came looking for waterfalls you can swim in Wyoming, here is the honest answer: dedicated swimmable waterfalls are essentially nonexistent in this state. Wyoming is hot-springs and river country. Its most famous waterfalls, including the dramatic falls in Yellowstone and Grand Teton, are protected viewing-only features where swimming is prohibited and would be extremely dangerous. Instead, Wyomingites soak in natural hot springs and swim in designated river stretches. The places people actually swim are Granite Hot Springs, Hot Springs State Park, Saratoga, and the designated river areas at Yellowstone National Park Swimming Spots. For the full picture, start with our Wyoming state guide and the hot springs and warm-water escapes guide.

This page exists for searches like "waterfall swimming holes Wyoming" and "waterfalls you can swim in Wyoming." Rather than pretend Wyoming has a hidden trove of swimmable falls, it redirects that intent toward the hot springs and rivers that genuinely define swimming here. Nothing below should be read as a guarantee of access, legality, or current conditions; always verify with official sources before you go.

Why Wyoming Is Hot-Springs & River Country (Not Waterfall Swimming)

Wyoming's natural swimming is overwhelmingly built around two things: geothermal hot springs and cold mountain rivers. The state sits on top of one of the most active geothermal systems on the planet, which is why soaking pools, not plunge pools beneath waterfalls, are the signature water experience here.

The waterfalls Wyoming is famous for, such as the Lower and Upper Falls of the Yellowstone River and the cascades of the Teton high country, are protected scenic features inside national parks. They are meant to be viewed, not swum. Approaching them means powerful current, slick rock, and long drops, and in many cases it is also prohibited. So while the search demand for "Wyoming waterfall swimming holes" is real, the responsible answer is to point you toward the hot springs and rivers below.

Where Wyomingites Actually Swim

These are the real, in-directory spots where natural swimming happens in Wyoming. Confirm fees, access, and current conditions with each managing agency before you travel.

Granite Hot Springs (Jackson / Hoback) — A remote developed pool fed by natural hot water in a forested mountain setting in the Bridger-Teton National Forest. It charges a fee and is famously open year-round, often reached by snowmobile or skis in winter. Verify road and facility status with the USFS before you go.
Hot Springs State Park (Thermopolis) — A Wyoming state park whose state-run bathhouse offers free mineral hot springs soaking (donations accepted), with indoor and outdoor options. Confirm hours and any time limits with Wyoming State Parks.
Saratoga (Saratoga / North Platte River) — The free, community-run Hobo Hot Springs pool, with the cold North Platte River right alongside it. The pool is free (donations welcome); the river offers seasonal river swimming when flows allow. Check local conditions before entering the river.
Yellowstone National Park Swimming Spots (Yellowstone NP) — Designated river swimming areas, most notably the Firehole River Canyon, where swimming is permitted in specific stretches. Access requires a Yellowstone park entrance pass, and swimming in or near thermal features anywhere in the park is strictly prohibited. Verify which areas are currently open with the National Park Service.

Waterfalls: Look, Don't Swim

Wyoming's iconic waterfalls are for the camera, not the swimsuit.

Yellowstone's falls (such as the Lower and Upper Falls in the Grand Canyon of the Yellowstone) are major protected scenic attractions with viewing platforms and overlooks. Swimming at or near them is not a thing, and approaching the rim or the river above the falls is dangerous and restricted.
Grand Teton's falls and high-country cascades sit in fragile, protected alpine terrain with frigid, fast snowmelt water. They are viewing destinations, not swimming holes.
Thermal areas are off-limits for swimming entirely. Yellowstone's hot springs, geysers, and runoff channels can be scalding and unstable. Swimming in or entering thermal features is prohibited and has caused fatalities. The only warm-water swimming in the park is in designated river areas where cooled thermal water mixes with river flow, not in the springs themselves.

If your heart is set on actual waterfall swimming, our waterfall chasers guide covers states where that genuinely exists.

When to Go

Summer (roughly June-September) is the window for river swimming. Snowmelt eases, water warms slightly from frigid to merely cold, and the designated river areas in Yellowstone and stretches like the North Platte at Saratoga are at their most approachable. Even then, mountain rivers stay cold and currents can be strong.
Hot springs are year-round. Granite Hot Springs is famous for winter access by snowmobile or ski, and the Thermopolis bathhouse and Saratoga's free pool operate across the seasons. Soaking is often most magical in cold weather.
Shoulder and spring season brings high, fast, very cold rivers from snowmelt; this is the worst time for river swimming and a great time for hot springs.

Conditions depend on snowpack, weather, and seasonal road status, so verify before each trip.

Water Safety

Thermal features are deadly. Never enter or swim in hot springs, geysers, or their runoff in Yellowstone or anywhere thermal. Water can be scalding, ground can be thin and unstable, and swimming in thermal features is prohibited. Stay on boardwalks and designated areas.
Cold, swift rivers. Wyoming's rivers are snowmelt-fed and stay cold even in summer, which can trigger cold-water shock and sap strength fast. Currents and submerged rocks and logs are common. Swim only in designated areas, never alone, and never when flows are high.
Never jump or dive. Depth and obstacles in rivers and pools are unknown and change constantly. Never jump or dive off rocks, ledges, or anywhere near a waterfall, and stay well away from the base and rim of falls.
Hot-spring health cautions. Soak time-limited, stay hydrated, avoid alcohol, and be cautious if pregnant or managing heart conditions. Very hot water raises body temperature quickly. Never put your head under in natural soaking pools.
No lifeguards. These are wild, unsupervised settings with limited cell service and slow rescue. Know your limits and turn back when in doubt.

Access & Permits

Access details change, so treat the following as a starting point and confirm with official sources:

National park entry: Yellowstone National Park Swimming Spots requires a Yellowstone park entrance pass. Verify fees, open swimming areas, and any closures with the National Park Service (nps.gov). Grand Teton also charges entry and has no swimmable falls.
State parks: Hot Springs State Park in Thermopolis offers free state-bathhouse soaking (donations accepted). Confirm hours and rules with Wyoming State Parks (wyoparks.wyo.gov).
Forest Service: Granite Hot Springs is on Bridger-Teton National Forest land, charges a fee, and depends on seasonal road or over-snow access. Verify status with the USFS.
Community pool: Saratoga (Hobo Hot Springs) is free and town-maintained; nearby North Platte River swimming is condition-dependent.

Leave No Trace / Thermal-Area Rules

Wyoming's thermal and alpine environments are fragile and unforgiving. Stay on boardwalks and established trails near thermal features, and never touch or enter hot springs, geysers, or their runoff. Pack out everything you bring in, including food scraps. Avoid soap, sunscreen, and lotions in or beside soaking pools and rivers, since residues harm both delicate microbial life and water quality. Keep groups small, respect wildlife and other visitors, follow all posted closures, and leave every feature exactly as you found it.
