Hot springs, waterfalls and swimming holes — mapped from public data
Three ways to get outside and get in the water, covered state by state. Every listing states its fee, access type and legal status up front, sourced from the land manager or park system rather than guessed at.
Knowing whether a place is actually open and legal to visit matters more than a pretty photo.

More states are being added as we verify access and legal status for each one.
Every listing states its fee, access type and legal status
Fee
What it actually costs to get in, from free roadside soaks to a resort day pass — and whether the price is cash only, seasonal or tiered.
Access type
Roadside, walk-in, timed reservation or a hike with mileage attached, so you know what the trip takes before you drive out.
Legal status
Who manages the site and on what terms: public land, a town-owned pool, a private resort, or access that is only informally tolerated.
How we build this
We haven't visited the sites listed here ourselves. This is a research-based guide, not a collection of trip reports. Every entry is compiled from public land-manager sources (the U.S. Forest Service, the National Park Service, the Bureau of Land Management and state park systems), federal datasets (USGS GNIS, NOAA's thermal springs archive) and published trail reports, with fees, access rules and legal status checked against the primary source and dated. When a site's access has changed, a closure, a new permit system, a fee increase, we say so and cite where that information came from.

Where the data comes from
Hot springs
NOAA/NCEI Thermal Springs List for the United States (1980), archived via PANGAEA. Temperatures are a historical estimate from the 1980 base survey, not a current reading.
Waterfalls
USGS Geographic Names Information System (GNIS), "Falls" feature class. Public-domain federal gazetteer data; confirms a named feature exists and its coordinates, not current trail conditions or access rules.
Swimming holes
No state or federal register exists for swimming holes. This list is hand-compiled from public park-service pages and other open sources, not a government dataset.
We haven't visited these places ourselves, and every page says so rather than implying otherwise. Details are compiled from public land-manager, USGS and NOAA sources and cross-checked where possible; conditions, access rules and fees change without notice, so confirm with the managing agency before you go.
