Hidden Gems – We Discover Agua Caliente Park in Tuscon

Have you ever just kinda bumped or happened into a place that you consider a hidden gem? We recently had one of those pop up on our radar.

While doing a Google Earth search for Jeep Trails in Tucson I noticed a pop up flag that said Agua Caliente Park, literally “Hot Water” in Spanish. After finding it I googled the name and found the parks website. This is a trip worth doing. The park is on the far East side of Tucson.

Park History

The 101 acre park has a long history. Human interaction with the spring goes back 5500 years. The spring flows periodically during the year and tends to flow more when it rains in the nearby Agua Caliente Mountains. This flow of water hrough faults between gneissic rock conglomerate sediment beneath the park, the area has probably been inhabited for thousands of years. There were originally two springs, a  “Hot Spring” and a “Cold Spring”.  The two springs produced a water flow of more than 500 gallons per minute (gpm).  In the 1930s, the springs were blasted in an effort to increase the water flow.  This had the opposite effect and reduced the water flow from 500 gpm to between 150 and 300 gpm and collapsing the two into one spring with a temperature of  around 72 degrees year around.  The spring was blasted again in the early 1960’s in another attempt to increase water flow, which unfortunately cut the water flow again down to around 100 to 125 gpm.  Throughout the years, the area has had many different purposes, from ranching to a health spa.  Most of the time the “ranch” term did not follow our traditional idea of a ranch but denoted an agricultural use in general

With the availability of water agricultural uses not typical of the Tucson basin could be implemented. An orchard contained at least 3000 trees of a wide variety of fruits.  Other types of ornamental trees were also planted or encouraged.  The huge mesquite tree east of the ranch house is estimated to be about 300 years old.

The oasis operated as a ranch and dude ranch for many years. It attracted many people because of its reputed “healing waters.” For a much broader view of the Parks History click here.

As I’ve pointed out this is a true oasis in the desert. If you visit the park you will find many walking trails and the old homestead. The park has undergone a restoration of the original pond to help reduce loss of water into the substrate. At this writing the pond is a beautiful aqua marine color due to the sealant that is being applied to the waters surface that eventually falls to the bottom and creates a nearly impermeable barrier.

Enjoy the day

This park is a shady and relaxing place for a picnic, just laying in the grass, reading a book, playing soccer with your kids on the lawn or hiking one of the level paved or gravel trails.
