Deep Creek Hot Springs, Natural hot springs in San Bernardino National Forest, California.

Deep Creek Hot Springs are natural thermal pools located in the San Bernardino National Forest foothills, where warm waters emerge along a mountain stream. Multiple bathing areas form at different temperatures, ranging from 38 to 40 degrees Celsius (100 to 105 degrees Fahrenheit), creating a series of accessible pools.

The springs lie on the Deep Creek fork of the Mojave River, in the rain shadow of the San Bernardino Mountains. The site is managed by the San Bernardino National Forest and maintained by a volunteer group, the Deep Creek Volunteers. The Pacific Crest Trail passes through the springs, which are also reached by the Bowen Ranch/Freedom Trail and the Bradford Ridge Path.

Bathing at the springs is clothing optional, and the site is maintained by a volunteer group, the Deep Creek Volunteers, rather than by paid staff. The Pacific Crest Trail runs directly through the pools, so thru-hikers share the water with day visitors arriving from Bowen Ranch or the Bradford Ridge Path.

Three different hiking routes reach the springs, including the Bowen Ranch Trail, Bradford Ridge Path, and Pacific Crest Trail, each demanding a good level of fitness. Visitors should prepare for desert conditions, carry ample water, and check trail conditions before heading out.

The endangered Southwestern Arroyo Toad (Bufo californicus) lives along Deep Creek beside the pools. The springs sit in a rain-shadowed ecotone where desert chaparral, montane chaparral, piñon-juniper woodland and conifer forest meet. Water from the creek and pools is not advised for consumption.
