A popular destination for hikers and off-highway-vehicle enthusiasts, the former military supply route makes a beautiful half-day drive that offers recreation, ranching and history. The graded dirt road winds its way up from the desert east of Tucson between the Santa Catalina and Rincon mountains and through oak- and juniper-dotted grasslands. It tops out over Redington Pass and descends into the San Pedro River Valley and the farming and ranching community of Redington.
