Wonder Valley Hot Springs

## Overview Wonder Valley Hot Springs is a remote geothermal spring located in the high desert of Wonder Valley, California, east of Twentynine Palms in San Bernardino County. Situated at approximately 34.1686° N, 115.8867° W, this spring lies within the vast Mojave Desert landscape — a region known for its geothermal activity along fault lines that crisscross the area. The broader Wonder Valley region has long attracted homesteaders, artists, and desert enthusiasts drawn to its stark beauty and off-grid character. The geothermal springs in this part of the Mojave are generally associated with deep fault systems that allow heated groundwater to rise to the surface. Historically, hot springs throughout the California desert have been used by Indigenous peoples — including the Serrano and Chemehuevi — for bathing and ceremonial purposes, though specific documentation for this particular site is limited. Wonder Valley Hot Springs sits in a sparsely populated stretch of desert terrain, far from major towns. Visitors should be aware that this is a rugged, remote location with no developed facilities, and conditions can vary significantly by season. ## Directions 1. From Twentynine Palms, head east on CA-62 (Twentynine Palms Highway) into Wonder Valley. 2. The spring is located south of CA-62 at the GPS coordinates 34.1686, -115.8867. 3. Use a reliable GPS or mapping application to navigate to the precise coordinates, as there are few road signs or landmarks in this area. 4. A high-clearance vehicle is recommended, as access may require traveling on unpaved desert roads. 5. Be sure to carry plenty of water, fuel, and supplies — services are extremely limited in Wonder Valley. ## What to Expect Wonder Valley Hot Springs is a true desert hot spring experience. The surrounding landscape is classic Mojave Desert — open, arid terrain with creosote bush, Joshua trees in the distance, and sweeping views of rugged desert mountains. Expect minimal shade and intense sun exposure, especially during summer months when daytime temperatures regularly exceed 110°F (43°C). The spring area is undeveloped, so there are no restrooms, changing areas, or other amenities. Water temperature and flow can vary, and visitors have noted that desert hot springs in this region can range from warm to very hot depending on the source and season. Exercise caution when testing the water temperature before entering. The best times to visit are during the cooler months, from late October through March, when desert temperatures are more comfortable. Night visits can be particularly rewarding, as Wonder Valley is known for its exceptionally dark skies and brilliant stargazing. Because this is a remote and unmanaged site, visitors should practice Leave No Trace principles — pack out all trash and respect the fragile desert environment. Cell phone service may be unreliable or nonexistent in this area, so plan accordingly and let someone know your itinerary before heading out.
