About Sierra Hot Springs
Sierra Hot Springs, California is a nonprofit retreat center and hot spring resort at 521 Campbell Hot Springs Rd in Sierraville, a small alpine community roughly 30 minutes north of Truckee in the northern Sierra Nevada. The property sits at approximately 5,023 feet elevation on 700 acres bordered by national forest land at the edge of the Sierra Valley.
Four soaking areas are available to visitors. The Temple Dome is the signature feature: a geodesic dome with stained-glass skylights that cast colored light onto a hot mineral pool maintained between 105 and 110 degrees Fahrenheit, flanked by two cold plunge baths. An outdoor warm pool adjoins the dome on a large sundeck overlooking the Sierra Valley. The Meditation Pool is a quieter outdoor pool with a natural sandy bottom set among pines. Private soaking rooms are also available in the Phoenix Bathhouse. All pools are fed by alkaline mineral springs at the source, with no chemicals added.
The resort operates as a sister property to Harbin Hot Springs in Lake County, and memberships are honored at both sites. A Philosophy Cafe on site offers seasonal meals. Workshops, yoga, and other wellness programming are offered regularly, giving the property the character of a retreat center as much as a hot spring resort.
Location & Access
Getting to Sierra Hot Springs
Sierra Hot Springs is reached from Interstate 80 by taking exit 188B in Truckee onto Highway 89 north, continuing approximately 30 minutes to Sierraville. In Sierraville at the intersection of Highways 89 and 49, turn right onto Highway 49, then right onto Lemon Canyon Road, and right again onto Campbell Hot Springs Road. Follow this road approximately 0.8 miles to the main lodge.
Free on-site parking is available. No hiking is required to reach the pools or lodge. The resort is open year-round, though mountain weather near Sierraville can bring snow in winter, and road conditions on Highway 89 should be checked before traveling in winter months. Highway 89 is a well-maintained state route and the approach road is paved.
Reservations are required for all visits; the resort does not accept drop-in visitors. All visits require at least one person in the party to hold a current membership, which can be purchased on arrival. Day use is offered Thursday through Sunday only. For visitors seeking hot springs near Truckee in a mountain setting with a retreat character, Sierra Hot Springs offers a distinctly different experience from the commercial ski resort atmosphere of the Tahoe basin to the south.
Suitability & Accessibility
Who Sierra Hot Springs Suits
Sierra Hot Springs suits adults seeking a clothing-optional retreat center experience in the northern Sierra Nevada, combining hot spring soaking with a communal, wellness-focused atmosphere. The resort is oriented toward adults and the clothing-optional environment throughout the property makes it unsuitable for families with children in the conventional sense, though overnight guests may bring children at an additional nightly charge.
The facility is not wheelchair accessible. The property spans forested terrain and the pools involve steps and uneven ground. No documented ADA provisions exist for the facility, and visitors with mobility needs should contact the resort directly before booking.
The resort's character is shaped by its nonprofit, community-run structure: guests are expected to contribute to the shared ethos of the space, which includes no smoking, no alcohol, no drugs, and no open flames on the property. This makes Sierra Hot Springs a good fit for visitors who appreciate a clean, substance-free environment, and a poor fit for those seeking a conventional resort experience. The combination of mountain scenery, stained-glass dome architecture, and natural mineral water creates an atmosphere that draws repeat visitors year after year to one of the more distinctive hot springs in California.
Safety & Etiquette
Safety and Etiquette at Sierra Hot Springs
Sierra Hot Springs is generally safe as a managed nonprofit facility with on-site staff, maintained pools, and clear community guidelines. The mineral pools reach temperatures between 98 and 110 degrees Fahrenheit, and standard warm water precautions apply: hydrate well, limit extended immersion in the hottest pool, and use the cold plunges to cool down between soaking sessions. The cold plunges are an integral part of the bathing circuit and are encouraged as part of responsible thermal soaking.
The resort has a strict no alcohol, no drugs, no smoking, and no open flames policy that applies throughout the property including camping areas. Guests who violate these rules are asked to leave. This policy is fundamental to the resort's character and is enforced consistently. Photography of other guests requires their explicit consent, which is particularly important in a clothing-optional environment where many visitors are unclothed.
Clothing is optional throughout the property. Guests who prefer to remain clothed are welcome, and the environment is described as non-judgmental. Quiet is expected at the pools, particularly in the Meditation Pool area. The Temple Dome is a shared communal space and guests should be respectful of other soakers' experience.
All visits require advance reservations; the resort does not accept drop-ins. Day use is available Thursday through Sunday only, and at least one person in the party must hold a membership. Memberships are inexpensive and can be purchased on arrival. The resort honors memberships from its sister property, Harbin Hot Springs. Pets, smoking, and alcohol are not permitted anywhere on the 700-acre property.
