Overview
A clothing-optional retreat built around hot water
Harbin is not a “stop for 30 minutes on the way through.” It’s a retreat property near Middletown with pools, hillside paths, and a community vibe that’s been part of Northern California soaking culture for decades. The soaking is clothing optional, and that shapes the feel of the place as much as the mineral water does.
The pools, in plain terms
Harbin’s own lodging information describes two pools at the Domes area, with the upper pool about 98°F (37°C) and a lower pool that’s ambient (unheated). Other parts of the property have additional soaking areas with their own rules and quiet expectations. The practical takeaway: you can usually find a temperature that feels workable, but you still need to pace your time in warm water.
A note on history and reopening
The property was damaged in the 2015 Valley Fire and partially reopened in January 2019. Today it operates as a hot springs retreat and workshop center, and planning ahead is part of the experience, especially for weekends and popular seasons.
Location & Access
Where it is
Harbin lists its address on Harbin Springs Rd near Middletown, in Lake County, Northern California.
By car
It’s drive-up access on rural mountain roads. The last portion can be winding, so plan extra time and avoid rushing after dark if you’re not comfortable on narrow roads.
Entry and planning
Harbin manages visits through reservations, day use, and lodging options that can shift by season. Check the official site for the current system, arrival windows, and any day-use limits.
What to bring
Bring a large water bottle, sandals, and a robe or cover-up (useful at clothing-optional sites for comfort between pools). Pack a warm layer for evenings, the hills cool off fast. If you’re sensitive to sun, add a hat and sunscreen for exposed walking paths.
Suitability & Accessibility
Harbin works best for adults who like unhurried soaking and don’t mind a retreat-like atmosphere. It can also work for families, but only if everyone is comfortable with a clothing-optional setting and the property’s kid-specific rules.
Families
Harbin’s posted rules include specific expectations for children, including supervision, time limits in warm water, and nighttime restrictions. If you visit with kids, treat it as a structured, short-soak experience, not an all-day pool hang.
Couples and solo travelers
Couples often like the quiet, off-grid feel without needing wilderness skills. Solo travelers do well here too, it’s easy to settle into a slow rhythm of soak, cool down, and walk the property.
Mobility realities
This is a hillside retreat with paths, grade changes, and wet areas around pools. Some areas may be easier than others, but I would not assume full wheelchair usability across the whole property. If step-free access is essential, ask the staff what zones and entries are realistically workable.
Expectations vs reality
Harbin is more “retreat” than “resort.” If you want polished luxury, choose a hotel spa. If you want hot water in a community setting with quiet rules, it’s a fit.
Safety & Etiquette
Clothing-optional etiquette
Be calm, be discreet, and don’t stare. Use a towel or robe when moving around if that makes you more comfortable. Respect personal space in and out of the water.
Kid rules and supervision
Harbin posts specific rules for children (including supervision and limits on where and when they can be in the warmest water). Follow them closely, they exist for safety and for keeping the atmosphere workable for everyone.
Heat pacing
Even 98°F (37°C) can wear you down over time. Rotate soaking with cool-down breaks and drink water. If you feel lightheaded, get out immediately.
Surfaces and footing
Wet steps and decking can be slick, especially at night. Move slowly and keep sandals on until you’re entering the pool.
Privacy and phones
Retreat settings rely on privacy norms. Keep phones put away in soaking areas unless you’re certain photography is permitted and you can avoid capturing other guests.
