Lake Arrowhead and Deep Creek Swimming Spots

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 crystal 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.
