Gilman Hot Springs
Gilman Hot Springs discharges at 117 degrees Fahrenheit, flowing nearly 52 degrees warmer than ambient in a modest but reliable system near San Jacinto.
The spring emerges from granitic alluvium terrain at 1,508 feet elevation, roughly 90 feet from Gilman Springs Road in landscape shaped by the San Jacinto River and Potrero Creek. The Inland Empire setting presents chaparral-covered hills and coastal sage scrub, creating a warm, dry environment well-suited to thermal features.
Roadside access from Gilman Springs Road. The semi-arid climate makes visits comfortable year-round, though late spring through early fall offers the best conditions. Limited parking and minimal facilities on-site; plan to visit as a short stop rather than extended stay.
Historically known as San Jacinto Hot Springs or the Relief Springs, this system took its modern name from the Mexican land grant Rancho San Jacinto Viejo that once covered this region. The springs form from groundwater heated by deep geothermal gradient and filtered through granitic rock before emerging at the surface.
