Rock Tub Hot Springs is located in the Long Valley Caldera that was formed over 700 thousands year ago by the collapse of a volcano roof 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 - the Hot Creek Geological Site.
The concrete and rock tub is about three feet deep and large enough for six people. The mineral water flows out of the hot springs source that located on the hill through a long pipe into this enticing tub. The water in the tub can be replaced by removing a drain plug on the bottom. One of the amazing features of this hot springs - the water temperature at this location are not scalding hot like Shepherd or Crab Cooker and, typically, is between 90 and 95 degrees Fahrenheit.
The tub is situated near the road but hidden down of the hill that gives the feeling of privacy if no one is there - rare case at the spring or summer weekends. This spot is very well-known and loved for relatively warm water, easy access, and breathtaking view on the snow-capped Sierra Nevada.
There is parking available at the lower area next to the tub. Please help to keep the springs clean by packing out all your trash.
