Gilroy Hot Springs flows at 106 degrees Fahrenheit within Henry W. Coe State Park, a California Historical Landmark and National Register property famed for Japanese heritage and Victorian architecture.

The spring settles at 1,147 feet elevation approximately 80 feet from the nearest road in the rugged Diablo Range terrain that defines Santa Clara County's backcountry. Historic structures surround the feature—an 1870s Italianate-Victorian bathhouse, a 1939 Buddhist shrine, and a Japanese garden teahouse—creating a landscape layered with cultural significance and natural thermal features.

History of Gilroy Hot Springs

Japanese immigrants developed this property beginning in the 1890s, establishing the bathhouse and later adding the shrine and teahouse during the 1930s. The spring's thermal output and mild elevation position made it attractive for early resort development, and its historical structures remain testament to cultural heritage and long-standing use of California's thermal features.

State Park access with day-use fees. The mild Mediterranean climate with 58.5-degree average temperatures makes visits comfortable spring through fall. Historic buildings may have limited access; contact the park for current visiting hours and any architectural tours offered.
