Mono Hot Springs

## Overview Mono Hot Springs is a remote geothermal hot spring area nestled in the Sierra Nevada mountains of central California, situated at approximately 6,500 feet elevation near the South Fork of the San Joaquin River. Located within the Sierra National Forest, this collection of natural hot springs has been a destination for soakers and nature lovers for well over a century. The hot springs at Mono Hot Springs emerge along the granite banks of the river, where geothermally heated water rises to the surface at temperatures that can exceed 100°F (38°C). The area features multiple spring sources — some pooled naturally among the rocks along the riverbank, and others that have been partially improved with stone or concrete soaking tubs over the years. The mineral-rich waters have historically been valued for their purported therapeutic qualities, and the springs have long been a gathering place for visitors seeking relaxation in a stunning alpine setting. The name "Mono" is derived from the Mono people (also known as the Western Mono or Monache), a Native American group indigenous to the central Sierra Nevada. The hot springs and surrounding area held cultural significance for indigenous communities long before Euro-American settlers arrived. By the early 20th century, Mono Hot Springs Resort was established nearby, offering rustic accommodations and access to the springs — a tradition that continues in some form today. The springs sit at GPS coordinates 37.3265, -119.0172, deep in the backcountry east of Fresno, California. The surrounding landscape is characterized by towering granite peaks, dense conifer forests, and the rushing waters of the San Joaquin River — making the journey to Mono Hot Springs as scenic as the destination itself. ## Directions 1. From Fresno, California, head northeast on CA-168 (Sierra Freeway) toward the town of Shaver Lake — approximately 50 miles. 2. Continue past Shaver Lake on CA-168 as it climbs into the Sierra Nevada, passing Huntington Lake. 3. Beyond Huntington Lake, the road becomes Kaiser Pass Road (Forest Road 80). This is a narrow, winding mountain road — drive with caution, especially in an RV or larger vehicle. 4. Cross Kaiser Pass (elevation ~9,200 feet) and descend toward the Mono Hot Springs area. 5. Follow signs for Mono Hot Springs Resort / Mono Hot Springs Campground. The total drive from Fresno is roughly 80 miles but can take over two hours due to the mountain roads. 6. The hot spring soaking areas are located along the South Fork of the San Joaquin River, accessible by short trails from the campground and resort area. **Note:** Kaiser Pass Road is a seasonal road, typically open from June through October depending on snowfall. Check with the Sierra National Forest ranger station for current road conditions before making the trip. ## What to Expect Visitors to Mono Hot Springs will find a series of natural and semi-improved soaking pools scattered along the rocky banks of the South Fork of the San Joaquin River. Water temperatures vary by pool and season — some pools are quite hot near the source, while others mix with cool river water to create more comfortable soaking temperatures. The mineral content gives the water a slightly sulfurous smell, which is typical of geothermal springs in the Sierra Nevada. The setting is spectacular: granite boulders, pine-scented air, and the sound of the river rushing past. Some pools are right at the river's edge, allowing soakers to alternate between hot spring water and the cold mountain river — a natural contrast therapy experience. Mono Hot Springs Resort, located nearby, has historically offered rustic cabins, a small store, and a bathhouse with hot spring-fed tubs. The adjacent Mono Hot Springs Campground (operated by the U.S. Forest Service) provides campsites for those who prefer to stay closer to nature. Both facilities are seasonal, generally operating from early summer through early fall. The area is remote, so visitors should come prepared with sufficient fuel, food, water, and supplies. Cell phone service is extremely limited or nonexistent. The elevation and mountain roads mean weather can change quickly, even in summer. A high-clearance vehicle is recommended but not strictly required for the paved (though narrow) Kaiser Pass Road. Because the springs are on National Forest land, there is no fee to soak in the natural riverside pools, though campground and resort fees apply for overnight stays. The area can be busy on summer weekends, so arriving early or visiting midweek offers a more peaceful experience.
