The Best Natural Hot Springs To Visit In Northern California

California is one of the best places to explore and enjoy natural hot springs. Explore with me as I travel throughout the Golden State to find the best natural hot springs across the state. Whether you are looking for a place to unwind and relax or have an adventure of a lifetime, in this guide, you will be sure to find the perfect hot springs resort in California.

Hot springs are formed by geothermal heat which forms when groundwater is heated. Geothermal means that the natural heat is produced within a layer of the earth. California’s active landscape pushes mineral-based springs to the earth’s surface, which creates the hot water in the steaming pools.

Alright – enough with the geography lesson, let’s get on to the good stuff!

Here is the guide to all the best natural hot springs in California:

Travertine Hot Springs, Bridgeport, CA

Travertine Hot Springs

If you are looking for hot springs with amazing mountain views, be sure to check out Travertine Hot Springs. The thermal springs are accessible by a dirt road which is only a few miles from Highway 395. You can drive right on into the first pools. Afterwards, make sure you walk a short distance to take in the epic views of the jagged Sawtooth Ridge as you enjoy and relax in the thermic bliss.

These pools range in temperature but the hottest one is right next to the parking area. When I say hot, the water is extremely hot. You could literally have a cup of boiling water ready for tea.

Make sure you test it out before jumping right in.

There are plenty of hot tubs to relax in, though. If you find the first few already occupied, head east through the maze of travertine rock and you will stumble upon 4 small pools in grassy meadow.

One of the best perks of these pools is that the bottom of the natural springs is mud, which can boost blood circulation and relieve pain. Take a deep breath, relax and enjoy the hot mineral springs.

Recommended stay: Walker River Lodge

TIP: Because the land surrounding the hot springs is Forest Service Land, you can legally camp for free in this area in any of the pullouts along the back roads. Be aware that it is primitive camping with no facilities so be prepared to bring in everything, including plenty of water for your stay.

LEAVE NO TRACE: Always practice Leave No Trace  ethics on your adventures and follow local regulations. Explore responsibly 🙂
