Sharkey Hot Springs is a BLM developed recreation site about 25 miles from Salmon off Highway 28, with two large concrete soaking pools of untreated natural hot water, heated changing rooms, vault toilets and an interpretive kiosk. The BLM rebuilt and reopened the site in 2002 after the 1920s-era plunge fell into disrepair.

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.
