The San Tan Mountain Regional Park is placed at the crossroads of diverse communities, regions, and cultures. The park is in demand to meet the needs of a regional area extending south from central Maricopa County and the East Valley of metropolitan Phoenix, into northern Pinal County. It is important that certain irreplaceable natural open space resources be preserved and that conservation management guidelines be established by the residents of the region to insure the integrity of the San Tan Mountains against degradation.

Located just south of the Maricopa/Pinal County line near the Town of Queen Creek, the San Tan Mountain Regional Park has been used for decades for various recreation activities such as hiking, equestrian riding, and wildlife photography. The park is rich with unique historical, cultural, and biological resources. This master plan seeks to provide programmed recreation activities that meet the needs of the existing users, future park visitors, and the growing East Valley population while protecting the park's natural, Sonoran Desert mountain environment. The master plan has considered both the 7,938 acres of currently designated park land and 2,260 acres of adjacent Maricopa County land.

Currently, the park consists of 10, 200 acres south of Hunt Highway in Pinal County. Restroom facilities and water are available at the San Tan visitor center.
