Bad Creek Spring
Bad Creek Spring flows at 81°F (27°C) in Lake County's volcanic highlands, a modest thermal discharge rising 21 degrees above the surrounding air temperature near Cobb.
The spring emerges at 1,679 feet elevation via short walk from Big Canyon Road through forested landscape. Volcanic ridges and oak woodlands characterize the terrain. The modest thermal output supports riparian vegetation where Bad Creek flows, creating a small oasis in the highland forest.
Bad Creek Spring sits within the Clear Lake volcanic field, sharing the geothermal character of its neighboring springs. The spring's modest temperature reflects limited heat flow compared to higher-temperature springs in the same volcanic system.
Reach the spring via short walk from Big Canyon Road through pleasant forest. Spring through fall offers the most comfortable visiting conditions. The nearby Warm Springs Recreation Area at Lake Sonoma provides additional day-use amenities. This spring appeals to visitors seeking quieter, less-visited thermal locations.
