Fish Creek Hot Springs
Fish Creek Hot Springs, also called Iva Bell Hot Springs, emerges at 110°F deep in Sierra National Forest's backcountry at 7,240 feet elevation. This remote wilderness thermal feature rewards dedicated hikers with pristine surroundings and water 65.8°F warmer than the high-elevation air temperature.
A strenuous 4.5-mile hike from the nearest trailhead reaches this spring, passing through mixed conifer forests and alpine meadows. Winter snowfall exceeds 200 inches annually, burying the area from November through May. The water's chemistry shows low dissolved solids (378 mg/L TDS) and neutral pH of 6.7, typical of pristine Sierra thermal sources. Crystal-clear streams flow from the spring.
Fish Creek Hot Springs sits atop a fractured rock system in the Sierra Nevada batholith where heat from Earth's interior drives groundwater toward the surface. The area's geological history spans hundreds of millions of years of tectonic activity and granitic intrusion. Indigenous peoples and early explorers likely discovered this site, though documented history remains sparse.
Access requires a challenging 4.5-mile hike on established trails; early summer through mid-fall offers the best conditions. Sherwin Creek Campground (13.2 km away) provides nearby camping with reservations available. The area falls within US Forest Service land with open public access; check local conditions before attempting the remote approach.
