About

The Soak Atlas is a travel-minded finder for hot springs: wild pools you hike to, historic bathhouses and roadside soaks. No app, no sign-up.

The list starts from OpenStreetMap (natural=hot_spring) and Wikidata, with US Forest Service and Recreation.gov records added for federal sites. We remove features that are not for bathing (geysers, fumaroles, mud pots, springs inside parks that ban soaking), entries that are clearly mis-tagged, and duplicates. NOAA's 1980 thermal springs list is used only to corroborate locations.

Where a spring has an official page, we quote what it says about fees, seasons, clothing and rules, word for word, with the date we read it. We don't judge whether a spring is safe.

The site is supported by display ads (off for now). For partnerships, email [email protected]. No spring pays to be listed or ranked.

Every detail on a listing shows where it came from and when. Details we have checked ourselves are marked ✓ with the date. Anything we don't know is shown as unknown. We don't guess.

Before you soak

Information only, not safety advice. Conditions, access, fees and closures change without notice, and water temperature and quality are not monitored by us. You soak at your own risk: check the official status link and posted rules on site before you go. We accept no liability for injury, loss or trespass.

Naegleria fowleri, a rare but nearly always fatal brain-infecting ameba, “thrives in warm freshwater lakes, rivers, and hot springs.” CDC advice: “Always keep your head above water in hot springs.” CDC, Naegleria fowleri Infections (page dated July 21, 2025) · checked 2026-10-15

Thermal water can scald. In Yellowstone, “Burns from thermal features are a common cause of serious injury and death in the park” and “it is illegal to swim or bathe in any water that is entirely of thermal origin.” We exclude springs inside Yellowstone, Lassen Volcanic and Hawaiʻi Volcanoes national parks.
