Northern California High Sierra Natural Mineral Hot Springs Resort
Mono Hot Springs Resort is about as remote as you can reach by automobile in California’s Sierra Nevada. Located between Yosemite and Kings Canyon on the west slope of the Sierra, the resort sits along the South Fork of the San Joaquin River, surrounded by granite peaks, pine trees, mountain air, and natural mineral hot springs.
Long before roads reached this part of the Sierra, local Mono Indians knew of the springs, and their history remains part of the story of Mono Hot Springs today. Whether you’re coming for a day soak, a rustic cabin stay, a camping trip, or a longer mountain retreat, Mono Hot Springs is a rare High Sierra getaway where you can slow down, soak, and enjoy the quiet beauty of the mountains.
To check current availability or make a reservation, call Mono Hot Springs Resort directly. Reservations are taken year-round by phone.
Getting to Mono Hot Springs in the Sierra “Range of Light”— Not the Mono Basin at Mono Lake
The route to Mono Hot Springs takes you into the Mono Hot Springs in the Central Sierra, known as the “Range of Light” of the western Sierra Nevada, not to be confused with Mono Lake on the east side of the Sierra. To get here from Fresno, you’ll travel over 9,100-foot Kaiser Pass Road, with views of the “Range of Light” and some of the most beautiful light-colored granite in the Sierra Nevada.
After about nine miles of paved road, much of it narrow and one lane, turn onto the well-marked Edison Lake Road. From there, the road drops down and crosses the San Joaquin River, with the turnoff to Mono Hot Springs Resort just past the bridge.
Before heading over Kaiser Pass, fill up with gas at Shaver Lake or Huntington Lake. No gas is sold at Mono Hot Springs or anywhere past Huntington Lake, and services are limited once you continue toward the resort.
When to Visit Mono Hot Springs
Mono Hot Springs is a seasonal High Sierra destination, typically open from late spring through fall, depending on snow, road access, weather, and mountain conditions. Because the resort is reached by Kaiser Pass Road, opening and closing dates can vary from year to year.
Summer is the easiest time to visit, with the warmest weather and the best access to the resort, river, lakes, trails, and natural mineral pools. Early and late season visits can be quieter, but visitors should always check current road and resort conditions before making the drive.
Ways to Access the Hot Springs
If you’re staying at Mono Hot Springs Resort, you can walk from your cabin or campsite toward the river and nearby natural hot springs. Cabin guests also receive free use of the hot springs spa and bathhouse, giving overnight visitors another easy way to enjoy the mineral water close to the resort.
Day-use visitors can park in the day-use parking area, then walk through the campground toward the river. If it’s your first visit, stop by the General Store for directions or ask for a facility map before heading out. Weekends can be busier, so quieter visits are often easier midweek or earlier or later in the season.
One common route is to walk from the day-use parking area through the campground toward the river, cross to the south side, and hike up toward Old Pedro and the nearby pools. Other springs may be reached from different paths or trailheads, depending on where you start.
Use caution around the river and pools, especially during snowmelt or wet conditions. Rocks, mud, concrete, granite, and river crossings can be slippery. Wear shoes with good traction, move slowly, bring drinking water, and keep a close eye on children.
Healthful Hot Mineral Baths
The Mono Indians first brought white men to the Hot Springs by horseback. Many were cured of their ills, so today Mono hot Springs are famous for their healing effects on arthritis, rheumatism and many other ailments.
The outdoor mineral spa is complemented by a spectacular view of 12,000 ft. Mt. Hooper.
Massages are available for 1/2 hour or 1 hour periods at reasonable rates.

Guide to the Natural Mineral Pools at Mono Hot Springs
After you reach the river area, you’ll find that the pools at Mono Hot Springs aren’t all the same. Some are hotter, some are cooler, some are easier to reach, and some feel more adventurous. The pools are part of a natural geothermal spring system, with mineral-rich water rising from below the earth’s surface and feeding the springs in different ways.
Be careful when stepping into any pool, since temperatures can vary from one spot to another. Test the water slowly before getting all the way in, respect other visitors’ privacy, keep noise levels down, and pack out anything you bring with you.
Here are a few of the main pools and soaking areas you’ll find around Mono Hot Springs.
Old Pedro
Old Pedro is one of the most well-known hot springs at Mono and one of the hottest. The water often averages around 106–107°F, with daily variation, so it’s best enjoyed in shorter soaks.
The two cement-lined pools are remnants of the 1934 bathhouse built by the Civilian Conservation Corps. The original bathhouse buildings are gone, but the historic concrete-walled pools are still part of the experience today.
Because Old Pedro is so warm, it’s more of an in-and-out pool than a place to stay for a long soak. Most visitors cool down after ten or fifteen minutes, then return when they’re ready. The pool is especially pleasant in the afternoon shade, with views up and down the San Joaquin River.
Reed Pools
From Old Pedro, continue uphill about 100 yards to reach the Reed Pools. These cement-lined pools are part of the same historic hot springs area, but they are usually cooler than Old Pedro, which can make them more comfortable on warmer days.
You’ll also see an old circular cement water tank nearby. Depending on the flow, warm mineral water may run from a pipe near the tank into a small tub below. The mineral water from this area is also piped across the river to the resort spa, giving guests another way to enjoy the hot springs.
Routes to Iodine Springs and Little Eden
From the Old Pedro and Reed Pools area, you can keep exploring toward several nearby hot springs. To reach Iodine Springs, walk east through the meadow for about 300 yards. This area can be muddy, but stepping stones may help you cross some of the wetter spots.
Little Eden can also be reached from above Old Pedro, but this route is steeper and more strenuous. Many visitors find it easier to reach Little Eden another way: return across the river, drive back out to Edison Lake Road, cross the bridge over the San Joaquin River, and park at the trailhead on the south side of the bridge.
Rock Garden
From the parking area, follow the path west along the river for about 100 yards. When you see water crossing the footpath, look uphill to your left toward the source. You’ll see a large granite outcropping with Rock Garden tucked beside it.
Rock Garden is one of the warmer hot springs, usually around 104°F near the spot where the spring water rises into the pool. It’s large enough for several people and has a beautiful natural setting, with maidenhair ferns growing above the water.
Mud Baths
From Rock Garden, follow the water uphill over the rocks for another 30 yards to reach the Mud Baths. This cooler pool has wide 180-degree views from sunrise to sunset, with the river flowing through the granite outcroppings below.
The soft clay lining the pool is also part of the experience and is often used as a natural facial. Because the surrounding rocks can be slippery, take your time getting in and out.
Iodine Pools
From the area where you climbed up to Rock Garden and the Mud Baths, continue about 140 yards farther down the path to reach the Iodine Pools.
These cement-lined tubs are deep enough to stand in and usually cool enough for a longer soak. Even in cooler hot springs, though, you can lose more water than you realize, so bring plenty of drinking water and stay hydrated.
Little Eden
Little Eden is one of the most scenic and surprising pools at Mono Hot Springs. It’s large enough to swim in and sits high on a ridge, with incredible views of the surrounding basin.
The easiest way to reach Little Eden is usually to return to the bridge over the San Joaquin River, drive about one mile up Edison Lake Road, cross the small grated bridge, and park in the recessed area above the bridge. From there, walk out onto the rocks below the road and look back toward the resort.
On hot days, Little Eden can be especially enjoyable because it’s often closer to swimming-pool temperature than the hotter soaking pools. From the area around Little Eden, you can take in views toward the Range of Light, Bear Dome, Devil’s Table, and the granite features that make this part of the Sierra so memorable.
Rose Garden
Near Little Eden is Rose Garden, a smaller and cooler pool where visitors can usually soak longer without needing to get in and out as often. It’s a good choice when the weather is warm or when you want a gentler soak after visiting one of the hotter pools.
A Little History of Mono Hot Springs
Mono Hot Springs has been drawing visitors for generations. Long before roads reached this part of the Sierra, local Mono Indians knew of the springs, and later helped guide settlers and travelers to the warm mineral waters by horseback and mule.
Over time, the springs became known as a place where visitors came to soak, rest, and seek relief from sore muscles, stiff joints, and the aches and discomforts of mountain travel. That old reputation is still part of the character of Mono Hot Springs today, where the warm mineral water, quiet setting, and High Sierra views continue to make the resort feel restorative.
The area became easier to reach after Kaiser Pass Road opened to the public in the 1920s. In 1934, the Civilian Conservation Corps built a bathhouse and several concrete-walled springs on the south side of the San Joaquin River. Some of those historic pools, including the Old Pedro area, are still part of the experience today.
The resort itself began soon after, when Walter Hill started building Mono Hot Springs Resort in 1935. Over time, the cabins, general store, café, and bathhouse helped turn this remote hot springs area into the rustic retreat visitors still come back to today.

Northern California High Sierra Natural Mineral Hot Springs Resort
What Makes the Hot Springs Geothermal?
Mono Hot Springs is part of a natural geothermal area, where water is warmed underground before rising back toward the surface. As the water moves through the rock, it picks up minerals and feeds the warm springs found throughout the area.
That natural process is what gives Mono Hot Springs its mineral water, warm pools, and unusual geothermal features, including nearby Doris Lake.
Visitors sometimes ask whether drought conditions affect the springs. According to a hydrologist who studied Mono Hot Springs, the water flowing from Old Pedro may have fallen as snow around 2,000 years ago. Because that water has been moving underground for so long, recent seasonal changes in rainfall haven’t had a noticeable effect on the spring’s flow.
Nearby Adventure: Doris Lake
Doris Lake is another local wonder, located about a mile north of the resort. This geothermally warmed lake doesn’t freeze in winter, and on the surface, a shallow layer of warm water can form above the colder water below.
To reach Doris Lake, follow the signs from the General Store and take the trail through the meadow just west of the cabins. It’s a moderate one-mile climb, and the trail comes out near the south side of the lake. Near the reeds, you may see bubbles from the hot springs rising to the surface. You may also see harmless garter snakes along the shoreline.
