Warm Spring, Hot Spring
Deep Creek Hot Springs flows at a robust 108°F in the San Bernardino National Forest near Lake Arrowhead. With 352 mg/L total dissolved solids and a sodium-sulfate composition, this is one of Southern California's most actively visited geothermal features.
The spring pools lie along Deep Creek at 3,520 feet elevation in desert mountain terrain where ponderosa pines and juniper intersperse among large granite outcrops. A 1,100-foot walk from 3N67/3N59 Road descends through mixed conifer forest to creek-side pools where flowing thermal water creates stark contrasts with the cooler mountain stream.
Deep Creek's geothermal activity reflects the Mojave Desert's underlying heat, expressed through faults and fractures in the Precambrian granite basement. The northern Mojave's geothermal provinces tap deep hot rock, with water circulating through these ancient crystalline structures.
Multiple pools and access points make this spring versatile for different experience preferences. North Shore Campground sits 8.2 km away, offering developed recreation options. The spring sits on federal land with multiple-use protection, guaranteeing public access for day-use geothermal exploration.
