Wild Willy's Hot Springs, also known as Crowley Hot Springs, is a spring located in Long Valley. Long Valley is home to one of the highest concentrations of geothermal surface water in California. Wild Willy's is surrounded by mountains in sagebrush plains, so you get to see a pretty view while you soak and relax in the natural hot springs.
There is a long wooden walkway that's about .2 miles long from where you park that leads you straight to the springs. The surrounding area is wide open with views of the Sierra Nevadas, making it quiet and peaceful if the springs aren't crowded, which they usually are.
There are a few pools here, the larger one attracting more people since it is deeper and has the capacity to accommodate larger groups. The smaller ones are a bit more shallow and are best for a couple people. The smaller pools are also usually hotter, making it feel more like a hot tub. The downside to these hot springs is that it attracts so many visitors because it is free and public.
The water temperature ranges from 95 - 105 degrees, depending on the day.
There are designated camping areas for those who prefer the overnight experience.
