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.
