Resorts · Desert Hot Springs, California, USA
Sea Mountain Inn
Sea Mountain Inn is a small, couples-and-women-only nude spa resort near Palm Springs — about 18 rooms, natural hot mineral water pools open 24 hours, and a day-spa-meets-lifestyle-lounge formula that has made it a Southern California institution. It is the closest thing the US West Coast has to a boutique lifestyle hotel.
What it's actually like
Sea Mountain runs on desert-spa rhythm: clothing-optional mineral pools and a large hot tub fed by Desert Hot Springs' famous aquifer, spa treatments by day, and a 24-hour lounge where DJ nights bring a lifestyle-leaning social crowd on weekends. The property is intimate — roughly 18 rooms with king beds and upscale linens — and day passes bring in a Los Angeles and Palm Springs crowd alongside overnight guests. The vibe is sensual and adult but boutique-scale: think candlelit pools and conversation, not a megaresort party.
Door policy shapes the room: couples and women only, 21+, with couples checking in together. That keeps the atmosphere social and low-pressure, and the inn enforces etiquette firmly. It is widely used by lifestyle couples as a weekend base, but plenty of guests are simply spa travelers who want adults-only nude sunbathing and mineral water.
Who it suits
US couples who want a lifestyle-friendly getaway without international flights — especially Southern Californians within driving distance. It suits travelers who prefer an intimate, spa-first setting over big-resort programming, and women travelers specifically, who are welcomed solo.
What first-timers should know
Book direct and read current policies: it is 21+, couples and women only, day passes and overnight stays are priced separately, and weekend nights are the social peak. Nudity is normal at the pools but optional; the lounge is more dressed-up. Palm Springs proper is 15–20 minutes away for restaurants and nightlife, which makes pairing the inn with a normal desert weekend easy.
Best time to go
October through May is prime desert season — warm days, cool nights, and the mineral pools at their most pleasant. Summer runs brutally hot (Desert Hot Springs regularly tops 105°F), which the 24-hour pools partially redeem after dark; rates drop accordingly. Weekends bring the social scene, midweek the quiet spa experience.

Common questions
Sea Mountain Inn, answered plainly.
Is Sea Mountain Inn a swingers resort?
It is a couples-and-women-only nude spa resort with a lifestyle-friendly social scene, especially on weekend nights. Like most US venues it operates within strict legal and house rules — it is best understood as a boutique adult spa hotel with a lifestyle crowd.
Can single men visit Sea Mountain Inn?
No — the resort admits couples and women only, 21 and over, and couples must check in together. Solo women are explicitly welcome.
Do you have to be nude at Sea Mountain Inn?
No. Pools and sunbathing areas are clothing-optional and most guests do go nude there, but it is a choice — and evening lounge culture actually leans toward dressing up.
Is there an age or membership requirement?
Guests must be 21+. Day spa passes and overnight stays are sold separately; check the resort's current pass policies and event calendar before you go, as weekend events can sell out.
