Mammoth Hot Spring
Mammoth, Wyoming4.7 (133 reviews on Google)
Mammoth Hot Spring is mapped next to Grand Loop Road in Wyoming, inside a quarter-mile snap. Treated here as an undeveloped backcountry pool; nothing on file corroborates that label. NOAA's vent measurement of 163°F sits in the scalding band. Access is priced as free and the amenities list is empty in our data. Treat clothing rules as unknown here until you get a local answer.
