From I-10, take I-19 South 1.2 mile to Ajo Way, Ajo Way west five miles to Kinney Road, turn right on Kinney Road. You will pass Tucson Estates, Old Tucson Studios, the Gates Pass access, McCain Loop, Desert Museum. Kinney Road turns north into the Park and the Red Hills Visitor Center. If you know nothing about Saguaro and the Sonoran Desert this is a must stop. No performance driving allowed on this narrow, scenic portion of Kinney Road please. When returning, try the McCain Loop for fun, but you will bypass the Desert Museum and have to back track on Kinney Road. The Gates Pass is a must drive for all Tucson visitors. See our Gates Passpage.
