Grizzly Spring flows at a modest 68 degrees Fahrenheit in Lake County, barely rising above ambient temperature and representing the cooler end of California's thermal spring spectrum.

Positioned just 25 feet from the nearest road at 1,311 feet elevation, this easily accessible feature sits within oak woodlands and grasslands characteristic of California's interior Coast Ranges. The landscape reflects seasonal precipitation and moderate temperatures, creating an accessible roadside stop in mixed oak habitat rather than a remote wilderness destination.

History of Grizzly Spring

Despite its low temperature differential, Grizzly Spring maintains thermal character through consistent flow and slightly elevated water temperature that suggests minor geothermal contribution or groundwater circulation through heated rock formations. The feature's proximity to Little Stony Campground area connects it to the broader Lake County geothermal system.

Roadside access without special permits. Modest temperature means water is lukewarm rather than hot; swimming conditions vary by season and surface temperature. The accessible location makes this suitable for casual roadside visits, particularly for travelers exploring California's geothermal diversity.
