About this app
Nanitch is the map of places to soak, sweat, and swim — hot springs, saunas, bathhouses, cold plunges, and clothing-optional beaches. Over 11,000 of them, worldwide. There are two kinds of spots here, and we always tell you which you're looking at. A hand-checked core: visited, moderated, and confirmed by members who have actually been there. And a much larger layer imported from OpenStreetMap — real places, correctly located, that nobody has confirmed yet. Those are labelled as exactly that. You will never be told something is verified when it isn't. Nanitch is completely free — no subscriptions, no ads, no in-app purchases. WHAT YOU GET - 11,000+ hot springs, saunas, onsen, bathhouses, cold plunges, swimming holes, and clothing-optional beaches. - "Know before you go": legal status, best season, access notes, where to park, first-timer tips, and live weather at each spot. - Member confirmations and freshness dates, so you can tell a solid spot from an iffy one. - Filters that matter: swimsuit or clothing-optional, good for a first visit, recently confirmed. - Ratings and SFW, pre-moderated photos from real members. - Save spots, track your visits, and earn badges as you explore. - Community events you can find and RSVP to. - Works on any phone — the map runs on the web too, no app required. BE THE FIRST Thousands of places on this map have never been confirmed by anyone. Go to one, tell us what it's actually like, and you're credited on it as the first person who did. BUILT FOR FIRST-TIMERS New to this? Nanitch tells you where you can actually go, whether it's legal, what the vibe is, and what to expect — with zero pressure. SAFE BY DESIGN Naturism here means non-sexual social nudity. There is no nudity anywhere in the app. All photos are SFW and reviewed before they appear. There is no private messaging — none, and there never has been. Report and block tools throughout, with active moderation. You must be 18+ to use Nanitch. SPOT SOMETHING OFF? Know a spot we're missing, or one that's wrong or outdated? Tell us instead of guessing — there's a "Suggest a spot or feedback" option right in the app (Me → Settings), or email us any time. We'd rather hear it from you and fix it fast. Help us keep the map honest. Some spot data © OpenStreetMap contributors, licensed ODbL. Nanitch — Chinuk Wawa for "to look, to watch over." Made in the Pacific Northwest.
Latest release
What’s New
The map just got a lot bigger. Nanitch now has over 11,000 places to soak, sweat and swim — hot springs, saunas, bathhouses, cold plunges and clothing-optional beaches, worldwide. Wyoming alone added nearly 600 hot springs. There are two kinds of spots now, and we always tell you which you're looking at: the hand-checked ones members have actually visited, and a much larger layer nobody has confirmed yet. Go to one of those, tell us what it's really like, and you're credited as the first person who did. ALSO NEW IN 1.1 Today — a new home tab. Who's out right now, what people have reported, and what's worth a look today. Plans — post an open meetup at a spot and let people join. There's still no private messaging, and there never will be. You meet by showing up. Nearby alerts — an optional heads-up when you're near a spot, and a two-tap way to report conditions for whoever comes next. Ask about this spot — a straight answer to "is this legal?", "where do I park?", "will it be busy?" What to expect — a plain-language summary on every spot. Conditions reports — crowd, water, parking, in a few taps while you're standing there. Photos — take one in the app, and heart the ones you like. The favourite becomes the spot's cover. Swimsuit or clothing-optional — a filter that's always visible, so you know what you're walking into before you go. A proper walkthrough — the app shows you around the four tabs the first time you open it, and you can replay it any time from Me. A faster map — rebuilt to stay smooth now that there are eleven thousand pins on it. Some spot data © OpenStreetMap contributors, licensed ODbL.
