Molly’s Hot Springs

Molly’s Hot Springs is a log-dam and rock-bordered pool in the Boise National Forest’s Warm Lake area, a quarter-mile from the forest road — the best-known soak of the Molly’s cluster, close enough to the road to stay popular but far enough to feel like a real find. Its temperature is adjustable via a hose-and-valve system fed from the source.

Red spider mites have been reported at this hot spring, so keep clothing and towels off the rocks and ground around the pools.

Pool Condition

The pool is bordered by a log dam and rocks, with a sandy bottom that tends to collect silt and algae. The trail to the springs and the South Fork Salmon River are both visible from the pool. A system of hoses and valves delivers hot water from the source, letting soakers adjust the temperature — but note that king-size soaks here can exceed comfortable temps (around 115°F) if the cold intake isn’t managed.

Seasonal Notes

Accessible all year. The dirt forest access road is not plowed during winter; access then is on horseback or snowshoe.

Camping

There is plenty of Boise National Forest camping nearby. There is no camping at the springs. Tilder (Steep) Creek Campground is just north of the springs, and additional hot springs sit within a half-mile radius — including Molly’s Tubs just up the road.
