- Best time to go: October-April for comfortable desert weather; winter weekends busiest with snowbirds — weekday mornings quietest. Summer soaking only early morning due to extreme heat.
- Clothing reality: Official: swimwear REQUIRED in and around the fenced pool area — nudity not permitted per posted BLM rules. Note: some directories still call it clothing-optional, reflecting an older reputation; current posted rule is suits on.
- Kids: Allowed.
- Cell service: ok — download maps and tell someone your plan.
- Accessibility: No-hike drive-up access from parking, but unpaved uneven ground and pools require stepping in — not wheelchair accessible in practice.
- Pools closed midnight-5am daily (posted hours) — this is a day-use-style facility, not 24 hr
- Soaking pools are FREE year-round; fees apply only for camping in the Hot Springs LTVA across the road — Sep 15-Apr 15: $180 season, $80/4-wk, $40/2-wk permit; Apr 16-Sep 14 free 14-day camping
- No reservations — LTVA permits first-come first-served from on-site host, BLM El Centro Field Office, or recreation.gov voucher
- Artesian well surfaces ~125F; pools cooled to ~104-110F — test water; valves adjust flow/temp
- No pets inside the fenced spring area (pets OK at camp under BLM rules); rinse at the shower pipe before entering
- Summer air temps routinely exceed 110F — the site is maintained by camp hosts mainly in the Sep-Apr snowbird season and essentially unmaintained in summer
- Also known as Highline Hot Well / Old Fogey Hot Springs; address ~3700 Evan Hewes Hwy, Holtville
- Hazard: 125F artesian source water at the well head — test pools first
- Hazard: Extreme summer heat (110F+) — dehydration risk
- Hazard: Unpaved uneven ground around pools
- Hazard: Desert sun exposure; limited shade
About this spring
Free BLM day-use hot spring beside Evan Hewes Highway ~6 miles east of Holtville: two concrete pools fed by an artesian geothermal well (main pool ~104-110°F), shaded by palms, with a rinse shower, benches and a vault toilet. Sits across the road from the Hot Springs Long Term Visitor Area, a major winter snowbird camping area. Day use only — closed midnight to 5am. No animals inside the fenced pool area. Best Oct-Apr; summer exceeds 110°F air temperature.
Fed by an artesian geothermal well surfacing around 125°F, Holtville's two concrete pools sit in a palm grove beside Evan Hewes Highway, directly across from BLM's Hot Springs Long Term Visitor Area — one of the bureau's winter snowbird camping hubs, where stays require a permit from mid-September through mid-April. Valves let bathers adjust the flow; the main pool holds roughly 104-110°F while the second runs a few degrees cooler, and overflow feeds a warm lagoon where swimming is not allowed. The mineral water is colorless and slightly salty, without the sulfur odor typical of many springs.
The site is also known as Highline Hot Well and Old Fogey Hot Springs. A BLM camp host cleans the pools periodically on no fixed schedule, and the water is untreated — visitors sometimes fill jugs with it. The facility is day-use only, closing midnight to 5 a.m., and no animals are allowed inside the fenced pool area.
Directions & trailhead access
From I-8 take exit 131 (Hwy 115 N/Van Der Linden), go east on Evan Hewes Highway ~3.8 miles; the pools are on the right, visible from the highway.
California geothermal context
California spans several geothermal provinces: the volcanic Cascades and Modoc Plateau in the northeast, Sierra Nevada granite seeps along the eastern front, Mojave and Colorado Desert springs in the south, and the famously mineral-rich Big Sur coast. Fire season (roughly June–November) closes access to many backcountry springs without warning — always check for current fire restrictions.
What a developed site means here
A developed site sits between primitive and resort: improved soaking infrastructure — built tubs, decks, stairs, sometimes changing rooms or vault toilets — often run by a land trust, nonprofit, or small operator. Expect modest fees or donation requests, posted etiquette rules, and more predictable conditions than a wild pool.
Best time to visit
Year-Round (Best: May – October)Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across California. Late spring through autumn offers the most comfortable road access.
