The Arizona Trail is an 800 mile long distance trail that runs the entire length of Arizona. It connects many different natural features including many mountain ranges, deserts, forests, canyons, other trial systems, historic sites, and more. Unlike many long distance trails, the AZT is open to mountain bikers as well as hikers, backpackers, and equestrians.
