Las Cruces Hot Springs emerges at 99°F within Gaviota State Park in Santa Barbara County, accessible via a short 350-foot walk from the Gaviota Peak Trail. The spring sits in coastal mountains north of Buellton and is sometimes called Gaviota or Sulphur Springs, indicating its modest but distinctive thermal output.

The spring lies 350 feet from the Gaviota Peak Trail in Santa Barbara County's coastal mountains where chaparral vegetation dominates hillsides. Annual precipitation reaches 13 inches, falling primarily during winter months. The surrounding landscape displays typical coastal range characteristics: steep canyons, exposed ridges, and coastal sage scrub adapted to Mediterranean climate conditions. The spring's 99°F water provides only modest warmth—38°F above ambient—typical of southern California's lower-temperature thermal features. Gaviota State Park protects this area, preserving open space north of suburban sprawl.

History of Las Cruces Hot Springs

Las Cruces Hot Springs—also known as Gaviota Hot Springs or Sulphur Springs—formed through geothermal circulation in the Santa Barbara County foothills. The moderate temperature and lower geothermal gradient suggest subsurface water heated through circulation at intermediate depths. The spring's presence indicates ongoing geothermal activity in coastal ranges, though of lesser intensity than volcanic regions. Historical use by local Chumash peoples and later settlers established its value despite modest thermal output. The spring sits within Gaviota State Park, which provides permanent protection.

Access requires 350-foot walk from the Gaviota Peak Trail, suitable for most visitors. State park day-use fees apply. Visit spring through fall when coastal mountains remain accessible; winter storms and rain can make trails muddy. Water temperature permits soaking but offers minimal warmth. Mt. Figueroa Campground lies 33 kilometers away with accommodations and views of wildflower displays during spring. Buellton and nearby Santa Ynez Valley offer full services, wine country attractions, and additional recreation opportunities.
