About this swimming hole
Wild Willy's Hot Springs is a chain of shallow natural pools scattered across the sagebrush flats of Long Valley, with the snowcapped Sierra crest filling the horizon. The free, clothing-optional pools run warm rather than hot, perfect for a long sunset soak. A short boardwalk from the dirt parking area leads across the meadow to the pools.
