Guide
Wild & Undeveloped Hot Springs.
These are natural hot springs recorded in OpenStreetMap as undeveloped geothermal features — primitive soaks rather than commercial bathhouses. Most have no staff, no admission gate, and no guaranteed facilities.
Conditions change: water temperature, flow, and legal access all vary with season and land status. Test the water before entering, pack out everything you bring, and respect any posted closures or private-land boundaries.
