Access

The Forest’s Mono Hot Springs Campground “sits above Kaiser Pass in the High Sierra, on the South Fork of the San Joaquin River” at 6,700 feet, and lists relaxing in the hot springs among the reasons to come. Getting there means Highway 168 east to Shaver Lake, on to Huntington Lake, then 17 miles of Kaiser Pass Road and 1.6 miles more; large RVs are not recommended on Kaiser Pass Road and the vehicle limit is 25 feet. A general store, post office and hot mineral baths sit at the adjacent Mono Hot Springs Resort. No drinking water at the campground itself.

Worth knowing: The Forest’s page covers the campground and the adjacent resort’s hot mineral baths; it publishes no description of individual natural pools at the site, so the distance class is an editorial band rather than a manager-verified route — verify locally.
