With over three million acres of forested hills, majestic mountains, and range land, Gila National Forest is best known for its wilderness areas, in particular the Gila Wilderness, the first wilderness in the United States. The magnificent mountain scenery, cool summer temperatures, and relatively warm winters permit a wide range of recreational opportunities during all seasons.

The Gila National Forest includes more wilderness than any other national forest in the Southwest. This undeveloped natural country can refresh the human spirit simply by its grandeur, purity, and remoteness.

The wilderness areas on the Gila comprise a vast, roadless realm astride the Black, Mogollon, Diablo, and Blue mountain ranges, varying from grassland foothills upward through juniper woodland, ponderosa pine, and then spruce-fir forests on the high peaks. Mountain meadows, aspen glades, and spruce forests border on narrow, rock-walled canyons which in some places plunge to depths of more than a thousand feet.

Three wilderness areas together total 792,584 acres or approximately 24% of the Gila National Forest. The Gila Wilderness, at 559,688 acres, is New Mexico's largest wilderness with an extensive trail system providing access. The Gila Wilderness, the world's first designated wilderness, was created on June 3, 1924, at the urging of the great conservation pioneer Aldo Leopold. The Aldo Leopold Wilderness lies to the east, while towards the west, the smaller Blue Range Wilderness adjoins Arizona's rugged Blue Range Primitive Area.
