Spanning over 1.7 million acres across southeastern Arizona and southwestern New Mexico, the Coronado National Forest is a vast and ecologically diverse landscape that includes the Pinaleño Mountains and Mount Graham — key landmarks of the Gila Valley. Managed by the U.S. Forest Service, this forest is part of the Sky Islands region, known for its dramatic elevation changes, rare wildlife, and world-class hiking, camping, and stargazing opportunities. The Safford Ranger District oversees local access points, including Swift Trail Parkway, Riggs Flat Lake, and Frye Mesa Reservoir, making the forest both a recreational treasure and an environmental sanctuary for the Gila Valley community.
