"Agua Caliente County Park is a regional camping park located in the Anza Borrego Desert and is best known for its geothermally heated springs. Three naturally fed pools provide different ways of enjoying the park's mineral water: There are two pools outdoors, and an indoor therapeutic spa is heated to 102 degrees and outfitted with Jacuzzi jets. The park is very popular during the winter and has numerous camping sites (full hook-ups, partial hook-ups, non hook-up and tent sites, and a caravan area for large groups) available. Hikers will enjoy miles of trails that meander through the park's canyons and across its hillsides."
