Spiers Springs
Spiers Springs flows at 79°F in the forested hills of Lake County near Cobb, situated in the geothermally active wine country thermal belt north of San Francisco.
The spring emerges at 1,419 feet elevation in the Mayacamas Mountains, positioned just 62 feet from Big Canyon Road for easy access. The surrounding landscape features oak woodlands and coniferous forests with 26.8 inches of annual precipitation, creating green rolling terrain in one of California's premier wine-growing regions.
This spring lies within the geothermal belt extending from The Geysers southward through the North Coast Ranges, an area of significant volcanic and tectonic activity that produces numerous hot springs. The region's thermal characteristics have long made it distinctive in California's landscape.
The roadside location near Big Canyon Road makes this spring one of Lake County's most accessible thermal features. The proximity to wine country, Lake Sonoma recreational areas, and the Warm Springs Recreation Area makes this a convenient addition to a regional visit. Access is straightforward year-round.
