The Arizona Trail is a once-in-a-lifetime experience, in that hiking it gets you enough of a leg workout for a lifetime. This famous trail stretches all the way from Mexico to Utah, more than 800 miles in total! And guess what, the trail is lucky enough to pass by Tucson. Hiking the nearby portion will take you through Colossal Cave Mountain Park, Saguaro National Park and the Santa Catalina Mountains. It’s a quick and easy stroll through some of the most beautiful landscapes Pima County has to offer.
