Located near Kenwood at just 340 feet elevation, this warm spring has attracted visitors since the 19th century and sits in one of California's premier wine-growing regions.
A short walk from the road through vineyards and oak savanna reaches Los Guilicos at 340 feet elevation near Kenwood. Warm water emerges into a natural pool surrounded by native oak and grassland typical of Sonoma County's transitional zone between coastal ranges and interior valleys. The 88°F discharge creates a comfortable thermal environment year-round in this mild climate.
Los Guilicos, meaning \little peaks\" or \"hills\" in Spanish

The 28-degree elevation above ambient (59.8°F) reflects moderate geothermal circulation in Sonoma County's geologically complex boundary zone. The warm waters attracted early spa development before modern conservation efforts established current protection."
