Unnamed Thermal Spring
This rare thermal spring emerges near Palos Verdes Estates at just 127 feet elevation, warming to 77 degrees—an unusual geothermal feature for the Los Angeles County coast.
The spring flows from fractured sedimentary rocks in the Palos Verdes Peninsula hills, located just a few meters from the road. Coastal vegetation frames the pool in this compact landscape where the thermal water stands out against the cool marine air and temperate surroundings.
The 77-degree water, warming the surrounding area by 14 degrees above ambient, indicates circulation through moderately deep geological pathways beneath the peninsula. This modest geothermal signature contrasts sharply with California's more famous thermal systems in the Sierra and volcanic regions.
Roadside access makes this spring easily reachable within the populated Los Angeles area. Expect mild year-round conditions typical of the coastal lowlands, with minimal seasonal variation affecting visitation. Water temperature remains steady throughout the year.
