Overall, it’s a 4,455-mile-long trail that extends across the U.S. from Canada to Mexico, passing through the states of Idaho, Wyoming and Utah, along with Arizona, and through 18 national  forests (including four in AZ). It stretches through a wide variety of AZ landscapes including stunning deserts and canyons, plateaus, woodlands, dense forests and alpine tundra. It’s recommended for ATV and UTV riders with more experience rather than less.
