Sol Duc Hot Springs Resort
Historic resort in a mossy old-growth valley of Olympic National Park with three mineral soaking pools (98-104F) plus a freshwater pool, drained and refilled nightly.…
Columbia Gorge · Carson, WA
Two primitive bedrock pools (102-105F) on the Wind River below the high-water mark, with hot water bubbling up through the riverbed. Submerged most of the year; reachable only in late summer to early fall when the river is low enough to cross.
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.
