Murrietta Hot Springs
Murrietta Hot Springs flows at a dramatic 132°F (56°C) in Riverside County—68 degrees above ambient air temperature—with high sodium chloride content and alkaline pH typical of important southern California thermal resources. The town of Murrietta Hot Springs itself developed around this thermal resource.
The spring sits virtually roadside (8 meters) on gently rolling terrain between coastal ranges and inland valleys at 1,180 feet elevation. The immediate landscape consists of chaparral and scattered oak, with exposed tan and red soils characteristic of the region. Mineral-rich thermal water flows through a landscape typical of inland Southern California foothills.
Murrietta Hot Springs has supported settlement since the late 1800s when its thermal properties attracted health seekers and resort development. The spring's high sodium and chloride content, elevated pH of 9.1, and consistent temperature reflect circulation through deep fractured rock and mineral-rich aquifers.
Roadside access makes this thermal spring exceptionally convenient—just a short stop from Camino Princesa. The spring remains open year-round; spring and fall offer ideal temperatures for visiting. Expect crowds from nearby communities. The mineral-rich, alkaline water should not be ingested; respect any posted access restrictions.
