• Rock Tub Hot Springs is one of the hot springs of the Long Valley Caldera
• Features a single soaking tub with a temperature between 90° and 95°F
Rock Tub Hot Springs is located in the Long Valley Caldera that formed over 700 thousand years ago when a volcano roof collapsed during a large volcanic eruption.
Rock Tub Hot Springs is a single soaking tub within a boundary of the ancient caldera east of Mammoth Lakes. Many hot springs dot this area including Crab Cooker Hot Springs, Shepherd Hot Springs, Hilltop Hot Springs, Crowley Hot Springs, and a geothermal wonder - Hot Creek Geological Site.
Made of rocks and concrete, the soaking tub is about three feet deep - large enough for six people. The hot water is transferred through a long pipe from the source that located on the hill. The water in the tub can be easily replaced by removing a drain plug on the bottom.
The water temperature at this location is not so hot as in Shepherd or Crab Cooker Hot Springs and, typically, is between 90 and 95 degrees Fahrenheit.
Though the soaking tub is situated near the road, it is hidden down of the hill that gives the feeling of privacy if no one is there - a rare case at the spring or summer weekends. This spot is very well-known and loved for relatively warm water, easy access, and breathtaking views of the snow-capped Sierra Nevada.
There is parking available in the lower area next to the tub. Please help to keep the hot springs clean by packing out all your trash.
The camping is not allowed at the hot springs but there are turnarounds and camping areas nearby. The best way to explore the area is stop by for a few days and enjoy this incredible geothermal area.
