About Slab City Hot Springs
Slab City Hot Springs is a small, informal geothermal soaking pool, a desert swimming hole of sorts at the edge of Slab City, an off-grid squatter community on the site of the former WWII Camp Dunlap Marine base near Niland, California. It has no official management or designation; visitors and Slab City residents ('Slabbers') soak in a warm, muddy pool with a faint sulfur smell, fed by an unclear underground source.
The spring sits in flat, sunbaked Imperial Valley desert near the entrance to Slab City, close to Salvation Mountain, amid water storage tanks and open ground with no landmarks or signage. It is part of the broader Salton Trough, a region known for active geothermal and gas-seep features (the nearby, much larger and hazardous Niland Geyser is a separate, unrelated site about 5 miles away).
Swimming at Slab City Hot Springs
A single circular pool of naturally warm water, reported around 98-104°F, with a muddy bottom, weak sulfur odor, and visible gas bubbling near its center. Visitors describe the water itself as genuinely warm and soakable, though water clarity and sanitary condition are questionable; it suits informal, low-expectation soaking rather than a polished hot-spring experience.
How to get to this swimming hole
Located just off Beal Road at the edge of Slab City, near Salvation Mountain and roughly 1.3 miles from the East Jesus art installation. One visitor account describes finding it by driving past a stand/gift-shop area and a cluster of water storage tanks into open desert ground, with no signage marking the spring.
The walk in
No real hike here. The water is a short walk from where you park. No trail or trailhead exists; the pool is reached by driving desert tracks off Beal Road into open ground near Slab City's entrance, then a short walk from wherever the vehicle stops. No source specified an exact walk time or distance.
Plan your visit
Bringing kids
Not ideal for young kids
Multiple first-hand accounts describe a muddy-bottomed pool with visible gas bubbling and a sulfur smell, an unregulated, unknown heat source, and questionable sanitary condition; one visitor flatly advises that people probably should not get in because the pools seem gross. There is no lifeguard, signage, fencing, or supervision, the site sits in an unmanaged squatter community (Slab City) with no facilities, and the broader region is known for CO2/H2S gas seeps. Suited to adults comfortable with a rustic, unsupervised soak rather than children.
Parking
Free
No formal lot or striped spaces; visitors drive informal desert tracks off Beal Road near the entrance to Slab City, past water storage tanks, and park informally near the pool. Access and parking are free, consistent with Slab City's unmanaged status. No source gave an exact walking distance from vehicle to the pool.
Restrooms
None on site
No restrooms at the spring itself. Visitors note the broader Slab City area 'has no running water or other facilities,' consistent with the site's unmanaged, off-grid status.
Water clarity
Varies with season and flow
Generally described as muddy/murky: hotspringers.net calls the water 'close to muddy water in sensory perception' with a muddy floor, and thedetoureffect.com says the springs 'seem gross.' However, loc8nearme.com notes the water 'will clear somewhat' if the pool hasn't been used for a little while, suggesting clarity varies with recent visitor traffic rather than being consistently clear or consistently murky.
Hours
Listed as open 24 hours, 7 days a week with free/unrestricted access (loc8nearme.com), consistent with the site having no official management.
On the water
Restrictions: Not applicable, this is a small, shallow natural soaking pool (on the order of a few feet across, per visitor photos/descriptions), not a boatable body of water.
No source mentioned kayaking, canoeing, paddleboarding, or any watercraft use here, and the pool's small size makes it unsuited for any.
What regulars say
First-hand visitor accounts offer mixed impressions. One visitor soaked in the evening and reported 'the water was indeed quite warm and felt good.' A more detailed account describes water around 104°F with a muddy bottom, weak sulfur smell, visible gas bubbling near the pool's center, partial concrete edging, an old faucet, and a wooden bridge over a discharge ditch on the south side, with sanitary condition described as questionable. Another visitor is more blunt, saying the springs 'seem gross' and that visitors 'probably should not' get in. Others add that the water clears somewhat if left undisturbed. Consensus across accounts: genuinely warm, informal, free, and unsupervised, with real water-quality caveats.
Backstory
The spring sits on the former grounds of Camp Dunlap, a WWII-era Marine Corps training base whose buildings were demolished by 1956; the abandoned concrete slabs left behind gave Slab City its name, and the site was later informally settled by squatters/RVers who use the adjacent hot spring.
