Holtville Hot Springs

What to expect

Holtville Hot Springs is not much to look at, and that is part of its charm. Two concrete tubs sit inside a fence on Bureau of Land Management land a stone’s throw from Interstate 8, about 19 miles east of El Centro in the Imperial Valley. Water from a geothermal aquifer is pumped up from a well and arrives at roughly 120°F49°C. You will also hear it called the Highline Hot Well, after the East Highline Canal next door, or the Old Fogey Hot Springs, a nod to the retirees who winter here.

The set-up, as of the most recent reports:

• The large tub is the hottest and deepest. It is about 5 feet deep, deep enough that an adult of average height sits in water up to the shoulders, and usually runs about 104 to 110°F40 to 43°C. Hot water enters below the surface, and a separate valve on a vertical pipe lets cooler, air-cooled water fall in.
• The small tub takes the overflow from the big one. It is shallower and a few degrees cooler.
• A stock tank has been added in some seasons. It seats about three, and its temperature depends on when it was last filled.

There is also a hot shower in the pool area. The overflow drains into a small pond ringed by palms just east of the tubs. A brush fire in December 2020 scorched those palms and the area around the springs, and the trunks are still blackened, but the tops grew back within a year.

Nobody comes here for scenery. People come because it is free, warm in winter and easy to reach, and because the regulars who camp across the road keep it in decent shape.

Getting there

The pools sit on the south side of Evan Hewes Highway, between the highway and I-8, just east of Holtville.

• From El Centro or San Diego: Drive east on I-8 about 18 miles past El Centro to Exit 131 (CA-115 / Van Der Linden Road). Head east on Evan Hewes Highway. Recreation.gov puts the long-term visitor area 3.8 miles along it. The fenced pool area is on the right, across the highway from the main camping area, just past the canal bridge.
• From Yuma: Drive west on I-8 to the same exit, roughly an hour’s drive.

The roads are paved all the way and suit any vehicle, including large RVs. Parking is a dirt area beside the fence. You walk a few steps to the tubs.

When to go

November to March is the season here. Daytime air temperatures in the Imperial Valley are mild, nights are cool, and the long-term visitor area fills with snowbirds. This is also when the tubs are cleaned regularly.

Summer is brutal. Air temperatures routinely pass 110°F43°C, and soaking in 105°F41°C water makes little sense. The tubs are not maintained as closely outside the permit season.

For a quieter soak, go before 9 a.m. or after sunset on a weekday. Campers say mid-day is the busiest time, and the volunteers drain and pressure-wash the tubs on Tuesday mornings, so plan around that.

Check status before you go. In April 2026 a camper reported on Campendium that a serious underground pipeline leak had appeared in mid-March, was eroding the entrance and had cut water pressure, and that BLM had talked about shutting the spring down. No closure has been announced by BLM that we could find. The BLM El Centro Field Office (760-337-4400, Monday to Friday) can tell you the current state of the pools.

Rules and etiquette

There is no fee to soak. The posted and reported rules are short:

• Closed from midnight to 5 a.m. The fenced pool area shuts for those hours, and overnight parking at the pool site is not allowed.
• Swimsuits required. This is a family-style public soak, not a clothing-optional spring. Visitors say people who undress are asked to put a suit back on.
• Shower first. Regulars expect it, and it keeps the water cleaner for everyone.
• No food, drinks, glass, soap or pets inside the pool area.
• Share the tubs. In peak season you will be soaking with strangers, often a lot of them. Courtesy keeps it pleasant.

Maintenance is done largely by visitors. BLM supplies cleaning gear, and campers drain the tubs, which have no drains, with a pump and then pressure-wash them. Some years the work has been done by a hired worker instead, and reviewers noticed the difference. If you find the water murky, that is the reason.

Where to stay nearby

• Hot Spring Long Term Visitor Area, directly across Evan Hewes Highway, is where most soakers stay. It is open desert camping with vault toilets, dumpsters and campground hosts, but no water, hookups or dump station. From September 15 to April 15 you need a permit: $40 for 14 days or $180 for the season, per Recreation.gov. The rest of the year, camping is free for up to 14 days.
• Holtville, about 8 miles west, has water fill and dump service at a storage business, plus groceries and gas.
• El Centro, about 15 to 19 miles west, has chain motels and full services.

Safety notes

• Heat: The big tub can reach 110°F43°C. Short soaks, plenty of drinking water and a slow exit are sensible, especially for older visitors. Do not put your head under.
• Deep water: The large tub is about 5 feet deep. Children and weak swimmers should not be in it unsupervised.
• Water quality: The tubs are refilled continuously and cleaned weekly in season, but no chemicals are added. Avoid soaking with open cuts, and skip it if the water looks slimy.
• Desert heat: Outside winter, the air itself is dangerous. Carry water in the car and never leave pets inside.
• Road noise and traffic: The tubs sit right beside I-8 and a busy two-lane highway. Watch for trucks when pulling out.

Nearby stops worth adding

The Imperial Sand Dunes (Algodones Dunes) begin roughly 20 miles east along I-8, and the biggest dunes are visible from the interstate as you drive toward Yuma. Yuma, about an hour east, has the riverfront and the Yuma Territorial Prison State Historic Park. If you are camping long-term, the canal service roads near the springs are popular with walkers and cyclists.
