Deep Creek Hot Springs

Natural thermal hot springs along Deep Creek in California's San Bernardino National Forest, reached by backcountry hiking and known for creekside soaking pools.

Deep Creek Hot Springs is a group of natural thermal soaking pools beside Deep Creek in California’s San Bernardino National Forest. The setting is undeveloped and scenic, with creekside pools reached by backcountry trails rather than a developed spa or resort.

The U.S. Forest Service describes the thermal springs within the Deep Creek corridor as regionally important, and Recreation.gov notes that the Pacific Crest Trail follows Deep Creek through this part of the national forest.

What makes Deep Creek Hot Springs different?

Deep Creek is not a developed thermal pool complex. The appeal is the combination of naturally heated water, a wild creek corridor and a rugged Southern California landscape. The surrounding drainage is environmentally significant. Recreation.gov says Deep Creek supports unusually diverse wildlife habitat within the San Bernardino National Forest and identifies the creek as a California Wild Trout Stream. The Pacific Crest Trail also follows the creek for part of its route.

Because this is a natural site, pool depth, temperature and creek conditions can vary. Visitors should not expect controlled temperatures, lifeguards, paved access or resort-style facilities.

Access and trail conditions

Deep Creek Hot Springs requires a genuine backcountry outing rather than a roadside stop. The terrain around Deep Creek is steep and exposed in places, and the return hike can be much harder than the descent. Conditions can also change because of heat, storms, wildfire restrictions, trail damage or temporary forest closures. Before travelling:

check the San Bernardino National Forest for current alerts and closures
check the weather forecast for the Deep Creek / Hesperia area
carry enough drinking water for the hike in and out
allow enough daylight for the return climb
do not rely on mobile reception being available
turn around if heat, water levels or trail conditions make the trip unsafe

The Forest Service currently lists Deep Creek Hot Springs as an open recreation destination, but that status can change and should be checked again immediately before a visit.

Soaking and water safety

These are untreated natural hot springs. Natural hot spring water is not disinfected or monitored in the same way as a commercial pool. Avoid swallowing the water, and take extra care to keep untreated warm freshwater out of your nose.

San Bernardino County Public Health specifically warns about Naegleria fowleri, a rare amoeba that can live in warm freshwater. The county documents a fatal 1991 infection following exposure at Deep Creek Hot Springs. The infection is rare, but the consequences can be extremely serious. Risk is associated with contaminated water entering the nose rather than with drinking the water. Practical precautions include:

avoid putting your head underwater
avoid jumping or diving into warm pools
prevent warm freshwater from entering the nose
supervise children carefully
leave the water if you feel unwell, overheated or dizzy

This information is not a substitute for current public-health advice. Check official health guidance before visiting.

Heat and dehydration

The hike deserves as much attention as the springs themselves. Deep Creek lies in an area where summer temperatures can become severe, and San Bernardino County emergency records document rescues of dehydrated hikers in the Deep Creek Hot Springs area. Plan conservatively:

carry more water than you expect to need
avoid starting a strenuous return climb during extreme heat
use sun protection
carry food and electrolytes
wear suitable hiking footwear
know your turnaround time

A soak at the bottom of the canyon does not reduce the difficulty of the hike back out.

Day-use setting

Forest planning documents identify continued day use at Lower Deep Creek and retain foot access to Deep Creek Hot Springs and the Pacific Crest Trail. Treat the springs as a fragile backcountry site:

pack out everything you bring in
avoid soap, shampoo and detergents in the pools or creek
do not alter or enlarge soaking pools
avoid damaging creek banks and vegetation
respect wildlife habitat
follow current fire restrictions and forest rules

When is the best time to visit?

There is no single guaranteed best season because access and weather vary. The most important factors are:

current air temperature
recent storms
creek conditions
trail condition
wildfire or forest restrictions
daylight available for the return hike

Extreme heat can make the hike dangerous even when the pools themselves are appealing. Check the forecast and official forest information rather than relying only on seasonal averages.

What should you bring?

For a typical visit, consider:

plenty of drinking water
sturdy hiking footwear
sun protection
food and electrolytes
a first-aid kit
offline navigation
a towel and dry clothing
a rubbish bag for packing out waste
enough time to complete the return hike before dark

Do not rely on the hot springs or creek as a safe drinking-water source without appropriate treatment.

Wildlife and environmental importance

Deep Creek is more than a soaking destination. Recreation.gov describes the drainage as supporting exceptional wildlife diversity and notes habitat for the endangered Southwestern Arroyo Toad. Visitors should stay on established routes where possible and avoid disturbing sandy creek-bank habitat. Responsible access helps protect both the springs and the broader creek corridor.
