US Natural Hot Springs, With Receipts
A searchable, mapped directory of 709 natural hot springs across 49 US states, with access details, clothing policies, temperatures, and source attribution.
Field notes
The directory combines geographic browsing with practical trip constraints: visible cards distinguish primitive/backcountry sites from resorts and community pools, while some entries include temperatures, clothing rules, and closure status. Its summary counts include 190 free-to-soak locations, 39 hike-in-only locations, and 38 marked clothing optional. The homepage also reports that 657 of 709 listings have a named supporting source, although the extracted page does not show the citation method or individual source records.
