Let us begin by looking at the hot springs steaming out of slopes of the eastern Sierra for those who have an appetite for boiled water. While technically not considered “swimming holes”, these natural wonders are a great place to soak on a summer evening and are relevant to this article due to the fact that you can only access these magma-boiled baths when the passes are open. A drive over Sonora, Ebbetts and Tioga pass will lead you to hot destinations such as Travertine Hot Springs, Buckeye Hot Springs and Hot Creek.
