Rio Rico is a planned community of 39,000 acres at the foothills of the Santa Rita Mountains, near the Santa Cruz River and the Sonoita Creek State Park. Once part of a vast land grant from the King of Spain, Rio Rico sits at 3,800 feet above sea level in the beautiful Sonoran desert. The community started in 1969 and it continues to grow today at a steady pace with the influx of new residents finding their way to southern Arizona.
