US Hot Springs Map
Updated September 2026 · 292 verified, visitable springs
Every pin is a verified, visitable hot spring — real coordinates, current open/closed status on the linked detail page. Closed, prohibited and view-only springs are deliberately excluded so nobody plans a trip to a dead end. Tap a pin for its full detail page: temperature, fees, access type, hazards and dated sources.
Pins cluster at low zoom — zoom in or click to open a spring's detail page.

Map FAQ
How many hot springs are on this map?+
The map shows every verified, visitable hot spring in our directory — the pins you see are real soakable destinations, not every documented thermal feature. (The US has ~1,600+ recorded thermal springs per the NOAA/USGS inventory, but most are geysers, seeps or scalding vents that nobody can soak in — we map the visitable subset.)
Which state has the most hot springs?+
Idaho by density — it has the largest soakable-spring concentration in the country (the Boise–Stanley corridor alone holds a dozen). California, Oregon, Nevada, Colorado and Montana follow. Use the state links below the map for each state’s own directory page.
Are the pins accurate to the exact spring?+
Yes — every pin uses the spring’s real coordinates, and each detail page carries a satellite-verifiable location. Status (open/closed/seasonal) shows on the linked page, pulled from the same researched record we publish — never a stale second copy.
Can I use this map offline?+
Not yet — but every spring detail page includes coordinates you can drop into offline tools (Gaia, onX, Google offline maps). A downloadable offline map pack is on the roadmap.
Why isn’t [famous closed spring] on the map?+
The map shows visitable springs. Famous closed or prohibited springs (Bagby, Skinnydipper, Austin) live on their own pages — kept out of the map so nobody plans a trip to a closed spot — but they’re searchable in the directory and the closed-springs tracker.
