Agua Caliente County Park: Hot Springs, Camping, Hiking

Agua Caliente County Park is a secluded campground 100 miles from San Diego, along County Route S-2. The Kumeyaay Indians were among the first visitors to the hot springs, known as Agua Caliente (“hot water” in Spanish). Spanish explorer Juan de Anza was the first European to visit the area in 1775. Historically, pioneers, soldiers, and prospectors utilized the springs at Agua Caliente, which also served as a stop on the Butterfield Overland stage route.

Agua Caliente County Park History

The Kumeyaay Indians initially utilized the hot springs, and were later discovered by Spanish explorer Juan Bautista de Anza in 1775. The springs also served as a stop on the Butterfield Overland Mail route. This stagecoach service, known as the Butterfield Overland Stage Route, operated in the United States during the mid-19th century. Along the route, there were several stations where horses could be changed and passengers could rest, with the stations typically spaced about 10 to 20 miles apart. Once the transcontinental telegraph line was completed, stagecoach service was no longer needed.
