Agua Caliente Springs
Agua Caliente Springs near Gila Bend flows at an impressive 102 degrees Fahrenheit at just 449 feet elevation, emerging 26 degrees above ambient in one of Arizona's hottest thermal features. This roadside spring exemplifies the extreme geothermal gradient of the low Sonoran Desert in Maricopa County.
Located just 51 meters from West Old Agua Caliente Road, the spring sits in classic low desert terrain with creosote bush, palo verde, and saguaro cactus. The landscape is flat to gently rolling, with minimal vegetation and sparse, widely-spaced shrubs typical of the Sonoran Desert's driest zone.
The high water temperature indicates shallow circulation through the hot basement rocks of the Basin and Range Province. The Spanish name references the springs' historical significance to indigenous peoples and early settlers seeking reliable warm water in this arid region.
This is the hottest thermal spring in the immediate area, making it suitable for soaking only with caution—test water temperature carefully before entering. Access is roadside convenient near Gila Bend; visit during cooler months for the most comfortable experience.
