Middletown · Lake County
Getting there. Historic clothing-optional retreat rebuilt after the 2015 fire. Reservation-based day-use + lodging; quiet, meditative pools.
Rules on the ground. Private retreat with its own rules and quiet policy. Reserve ahead.
If it is your first time. The classic NorCal clothing-optional retreat. It's a 'silence and stillness' vibe, not a party. Book in advance.
Near Ukiah · Mendocino
Getting there. Rustic clothing-optional resort west of Ukiah — tubs, a sauna, a rock pool, gardens. Reservation-based day-use + lodging.
Rules on the ground. Private facility, clothing-optional throughout. Reserve ahead; small and popular.
If it is your first time. Intimate and old-school. No phones, mellow crowd. Reserve well ahead, especially weekends.
Near Williams · Lake County
Getting there. Off-grid clothing-optional historic resort — long flumes of mineral water, remote high-desert setting. Reservation-based; day-use + lodging.
Rules on the ground. Private off-grid facility with its own rules. Reserve ahead.
If it is your first time. Remote, quiet, and unplugged. A destination soak — not a quick stop. Confirm it's open and book ahead.
These come from OpenStreetMap. They are real places at real coordinates, but nobody has been to them for us yet, so there is no write-up — no parking notes, no word on whether the road is open, no clothing policy. We label them exactly that way rather than pretending otherwise.
If you go to one, you can be the first person to confirm it, and you stay credited on that spot permanently.
Takes about a minute, and you do not need an account.
