There are numerous natural hot springs located on the Kern River canyon, most of them on the Lower Kern in between Lake Isabella & the Bako citrus orchards. Many are closed off to the public - private property. Lower Kern Canyon on Highway 178 is the way to Kernville California & inside the southern portion of Sequoia National Forest. And yes, nudity is the norm at most hot springs, so offended families consider yourself warned.

Kern Hot Springs: [BACKPACK IN ONLY]
Backpack hiking trails lead from Jerky Meadow near Forks of the Kern into wild backcountry. This one is an overnight hike for sure, so you need to be prepared with topo maps, gear and supplies for wilderness travel on foot. Horses are also a common form of transportation. This springs location is on the High Sierra Trail south of Mount Whitney... in the remote Upper Kern River.
