Wilbur Hot Springs - Day-use fee or pay-per-soak in Williams, CA (2026)
A solar-powered nature reserve where rustic hotel rooms and tent platforms overlook the south fork of Cache Creek.
Wilbur Hot Springs is a solar-powered nature preserve and rustic retreat in northern California's Cache Creek wilderness — about 2.5 hours north of San Francisco — with three covered flume soaking tubs (sulfur water at temperatures up to 112°F), historic hotel rooms, tent platforms, communal kitchen access, and zero-electricity-after-dark policy enforcement. The flumes are the marquee soak: long covered cedar troughs running mineral water at descending temperatures, where visitors sit individually or in small groups for as long as they want. Day passes start at $65; overnight stays add the after-hours and dawn soaks that day-trippers don't get.
What to expect
Reserve ahead — Wilbur caps capacity strictly. Drive Highway 20 from I-5, then a rough graded road to the property. Check in at the historic 1915 hotel building. Soaking is in three covered flume tubs (multiple individual sections in each), a swimming pool (cooler), and the Fluminarium (a historic indoor mineral pool). Communal kitchen for self-catered meals; bring groceries. No on-site restaurant. Cell signal is zero. Solar power is the energy source; lights go off after sunset in non-essential areas.
