Hot Springs in California

Timing your visit to California's hot springs can make all the difference. Spring and fall often offer the best balance of comfortable air temperatures and manageable crowds. Summer brings the most visitors to popular springs, so consider weekday visits or early morning arrivals to secure a peaceful soak. Winter transforms many mountain springs into magical settings where steam rises against snow-covered landscapes, but access roads may require chains or four-wheel drive. California hot springs on USFS and BLM land are generally open for day use; some require Adventure Passes or recreation passes. The California State Water Resources Control Board regulates thermal water rights. Springs in national forests may have seasonal closures for habitat protection. Clothing-optional policies vary by location. Mono County and Inyo County have specific ordinances for popular Eastern Sierra springs. Always check local fire restrictions during wildfire season. Check seasonal closures and permit requirements before heading out, and always have a backup destination in case your first choice is full or inaccessible.
