Galiuro Wilderness, Wilderness area in southern Arizona, United States.

Galiuro Wilderness is a 76,317-acre protected area covering the mid to upper slopes of the Galiuro Mountains in Arizona's Coronado National Forest. The range is a block-fault uplift cut by Rattlesnake and Redfield canyons, rising from 4,000 feet to Bassett Peak at 7,671 feet. Slopes carry manzanita, live oak and juniper, with cypress and pines in canyon bottoms.

The area received initial protection in 1932 and became a designated wilderness through federal law in 1964. This status secured the landscape against development and preserved it for future generations.

The Power family homesteaded in Rattlesnake Canyon in 1909 and mined nearby. On February 10, 1918, deputies came to arrest two sons for draft evasion; a gunfight at the cabin killed Sheriff Robert F. McBride, two deputies and Jeff Power. The cabin joined the National Register of Historic Places in 1975.

Trails here are minimally maintained with few markers, so bringing detailed maps and navigation tools is essential. Visitors should prepare for rough terrain and remote conditions where assistance is far away.

Within the mountains lies the wreckage of a World War II bomber that crashed in January 1943, killing its entire crew. A memorial plaque at the site honors the eleven service members who perished in this tragedy.
