"A small, warm spring that forms an inviting oasis in the middle of the dry Sonoran Desert. Although Agua Caliente is a beautiful setting, the spring is not a place to bathe as it is within a small county park. Agua Caliente is conspicuous due to its verdant palm tree grove, standing in stark contrast to the more subdued colors of the surrounding desert. The spring itself lies within a grove of palm trees, at the east end of the park, near some picnic tables.
The spring bubbles out of the ground at about 85 degrees F, crystal clear. The water flows downhill in a small creek, surrounded by dense palm tree growth. Within the water live several types of fish, and a variety of water insects. The water eventually flows into a large pond, frequented by several ducks. Below this largest pond, the water flows into two more ponds. Trails link all these ponds together. The spring has not been developed, although several pools have been formed from its runoff. The spring is located within a county park with picnic tables, restrooms, and older buildings."
