About Holtville Hot Springs
Holtville Hot Springs, California is a free BLM hot spring at 3700 Evan Hewes Highway in Holtville, in the Imperial Valley desert approximately 19 miles east of El Centro and beside Interstate 8. Two concrete pools are fed by an artesian well surfacing at about 125 degrees Fahrenheit; water cools to 104 to 110 degrees in the main pool and slightly cooler in the second pool. Valves allow visitors to adjust flow and temperature. A shower pipe at the entrance is used for rinsing before entering. Benches, shade, and a vault toilet are provided. No entry fee. Closes midnight to 5am. No animals inside the fenced area.
The spring is set in a grove of palm trees creating an oasis in the open desert. Water overflows from the pools into a warm lagoon pond at approximately 90 degrees; swimming in the lagoon is not permitted. The mineral water is colorless, slightly salty, and without a strong sulfur odor. Pool cleanliness is maintained periodically by a BLM camp host; condition varies.
The BLM Hot Springs Long Term Visitor Area across the road draws thousands of snowbirds each winter. This is one of the most accessible free natural hot springs in California, requiring no hike. Also known as Highline Hot Well and Old Fogey Hot Springs. Best visited October through April; summer temperatures regularly exceed 110 degrees.

Suitability & Accessibility
Who Should Visit Holtville Hot Springs
Holtville Hot Springs suits families, snowbirds, desert road travelers, and anyone seeking a free drive-up mineral hot spring in the Southern California desert.

Safety & Etiquette
Safety at Holtville Hot Springs
Holtville Hot Springs is generally safe to visit with conditions to be mindful of. The artesian mineral water enters the main pool at approximately 104 to 110 degrees Fahrenheit. Test the water before entering and use the valves to lower the temperature if needed. Do not soak for extended periods without breaks, particularly on warm desert days. Guests with cardiovascular conditions, pregnancy, or other health concerns should consult a physician before soaking.
Pool cleanliness is variable and noted in multiple visitor accounts as a concern. The pools are cleaned periodically by a BLM camp host but on no fixed schedule. Algae and organic matter have been reported at times. Visitors with open wounds, skin conditions, or compromised immune systems should assess pool conditions before entering. The water is not chemically treated.
The facility closes midnight to 5am. Overnight parking at the spring site is not permitted; BLM rangers patrol the area. No animals of any kind are permitted inside the fenced enclosure. Do not enter the adjacent lagoon pond.
Summer heat is the most serious safety hazard at this site. Imperial Valley summer temperatures exceed 110 degrees and the combination with hot pool soaking creates rapid dehydration and overheating risk. Summer visits are strongly discouraged. In cooler months, bring drinking water and stay hydrated throughout your visit. The nearest medical facilities are in El Centro approximately 19 miles west. No emergency services are on-site and cell coverage can be limited in this area.
