Mazatzal Wilderness, Protected wilderness area in Arizona, United States.

Mazatzal Wilderness is a protected area in Arizona covering mountain ridges, deep canyons, and several distinct vegetation zones. The landscape ranges from desert brush at lower elevations to dense pine forests higher up, creating varied terrain throughout the region.

The Mazatzal Wilderness, about 390 square miles in Yavapai and Gila counties, lies within Tonto and Coconino national forests and is managed by the U.S. Forest Service. Congress designated it under the Wilderness Act of 1964, which set aside roadless federal land; the Mazatzal range was among Arizona's additions to that system. Its 240 miles of trails, including the Verde River and Mazatzal Divide routes, date from later Forest Service work.

The name Mazatzal is commonly traced to Nahuatl, a language of central Mexico, though the mountains lie in central Arizona. The wilderness spans Yavapai and Gila counties, and the Tonto and Coconino national forests administer it. The Verde River Trail follows the river for about 28 miles along the western edge.

This area has limited marked trails and no developed facilities, so bring plenty of water and navigation tools for your visit. Good planning is important since help can be hard to reach in such a remote location.

The Verde River Trail follows the river for about 28 miles (45 km) along the wilderness's western edge, while the Mazatzal Divide Trail runs north–south for about 29 miles (47 km). Together they are part of roughly 240 miles (390 km) of trails crossing the area. Elevations run from 2,100 feet (640 m) at Sheep Bridge to 7,903 feet (2,409 m) on Mazatzal Peak.
