Also known as Kupa, Jojopin, and Aqua Caliente, Warner Hot Springs has been a little piece of heaven no matter what it has been called. Located in northeast San Diego County in the historic 47,000-acre Valle de San Jose, Warner Hot Springs is surrounded by the vast lands of the Cleveland National Forest, Los Coyotes Indian Reservation, Palomar Mountain, Bureau of Land Management, and Vista Irrigation Water District. Blessed with a four-season climate at an elevation of about 3,200 feet, it sits at the base of 6,500-foot Hot Springs Mountain, the tallest in San Diego County. Home of Native Americans, Spaniards, and white settlers, cowboys, and ranchers, Warner Hot Springs has played host to passing immigrants, Butterfield Stage passengers, vacationers, and movie stars. The world-famous hot springs have drawn people since the beginning of time. An early brochure states, It's where you will have some of the best days of your life, and many would agree.
