Gaviota Hot Springs is a small hot spring complex in Gaviota State Park on the California coast, long known to Indigenous people and later associated with Rancho Las Cruces. By 1880, nearby businesses were promoting the springs’ medicinal value, and late 19th-century visitors used them as a rustic camping and bathing spot. Early 20th-century government accounts recorded four warm sulphureted springs on Las Cruces ranch, where the water was piped for ranch use rather than developed as a resort. Today the site includes two soaking pools, one built in the 1930s, and is valued as a modest geothermal retreat shaped by local history and geology.
