Seigler Springs
Seigler Springs emerges at an impressive 126°F in Lake County's volcanic landscape, where a historic 19th-century resort developed around these powerful thermal features. The 68-degree temperature rise reflects robust geothermal circulation through the region's volcanic geology.
The spring sits virtually roadside at 2,293 feet elevation near Cobb, accessible just 31 feet from Seigler Canyon Road. The surrounding volcanic terrain features pine and oak forest, with seasonal creeks and mountain vistas. The area is heavily forested compared to California's lower-elevation thermal springs.
Seigler Springs became a resort destination in the 19th century, with major expansion in the 1930s and an airport opening nearby in 1947. The resort experienced decline in the 1960s, but the springs remain geologically significant as windows into Lake County's volcanic history.
The spring is readily accessible from Seigler Canyon Road. Visit spring through fall for comfortable mountain-forest conditions. Winter snowfall (5 inches annually) may affect access. Respect any private property or closure notices on the grounds.
