Before you go

Temperatures are measured at the source and can be far hotter than any soaking pool. Test with a hand before stepping in.
Access, fees, and road conditions change. Verify with the land manager or owner; "public" here reflects survey records, not a current right of entry.
Water in natural springs is untreated. Keep your head above water and avoid soaking with open wounds. Some springs carry Naegleria fowleri risk.
Pack out everything, including soap residue. Many springs have been closed because of trash and overcrowding.
