Catalina State Park covers 5500 acres at the base on the Catalina mountain range near Tucson.  The trail system explores foothills, canyons, and streams (with seasonal water crossings) amid desert flora and fauna.  Visitors can hike, bike, ride horses, and go birding.  Or run on all of the trails in one day.
