Rock Tub Hot Springs is located in the Long Valley Caldera that formed over 700 thousand year 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.

  1. Things have changed greatly since the 70’s when I explore most of the hot springs from California to Colorado. It’s amazing to find the information so readily compared to my search with the USGeothermal Book. everything was plotted out on a map and I had to find them the ol’fashion way with a compass. Some springs were used as cattle trough drinking, others were behind barbed wire fencing. The best of course were the pools built along side rivers. Such an exciting time. Thank you for taking the effort in creating this website.
