Central Idaho mountains · Salmon, ID
A chain of six waterfall-fed rock pools strung along Warm Spring Creek in the Salmon-Challis National Forest, reached by a steep two-mile hike gaining 1,350 feet. The upper pools run hottest near 113°F, cooling as creek water blends in lower down. Remote, scenic, and one of Idaho's most photographed wild soaks; free on BLM land with no reservations needed.
No reservations — wild springs are first-come, first-served. Some trailheads require a parking pass or day-use fee, so check the listing details and current land-manager rules before you go.
Swimwear and a towel, drinking water, a trash bag (pack out everything, including food scraps), and a headlamp if you're staying for sunset. Never bring glass near a wild spring — broken glass in a pool ruins it for everyone.
Wild spring temperatures shift with seasons, rainfall, and river levels — a pool that's perfect in October can be scalding or flooded in May. Test the water with a hand before getting in, and check recent trip reports for current conditions.
