History of Wild Willy’s Hot Spring

Wild Willy’s is one of many natural hot springs in the Long Valley region. The hot spring is believed to be the result of volcanic activity from thousands of years ago. The very same activity that resulted in the formation of the nearby Sierra Mountains. Wild Willy’s Hot Spring was regarded as “sacred” ground by early native Americans and early American settlers in and around the Mammoth Lakes area and the hot springs today maintain a rustic feel. The hot spring is currently managed by the BLM and Mono County, and everyone who visits is encouraged to enjoy the facility without leaving a trace. This is critical for the preservation of Wild Willy’s for future generations.

Camping Information

Wild Willy’s Hot Springs is located on public land, so you are free to camp if you want to. You will, however, want to take along all required amenities – from tents to sleeping bags and anything additional that you might need for the most comfortable camping experience. There are also no toilet facilities at the Wild Willy’s Hot Springs, so you will need to properly bury any fecal matter left in the area deep under the earth.
 

Seasonal Access Information

While accessible year-round, the pools tend to be crowded at times, especially on weekends and holidays when outdoor enthusiasts are out in force. If you visit during the week, it is likely that there will be fewer people to contend with and you will enjoy a more laidback and peaceful soaking experience. Please note that during inclement winter weather the BLM often gates (closes) the access road.
