Consisting of over 10,000 acres, the southeast Valley park is a fine example of the lower Sonoran Desert. The park ranges in elevation from about 1,400 feet to over 2,500 feet. Goldmine Mountain is located in the northern area, with a spectacular San Tan Mountain escarpment in the southern portion of the park. The vegetation changes from creosote flats to dense saguaro forest. Various types of wildlife may be observed, including reptiles, birds, and mammals. Amenities are slated for future development.

San Tan Mountain Regional Park also has a Visitor's Center. Don’t forget to stop by the Visitor's Center to pick up educational tidbits, purchase souvenir items, visit with park staff, and see the wildlife exhibits or tortoise habitat. Restroom facilities are available and additional amenities are slated for future development.
