Wilderness

The Gila National Forest boasts three designated wilderness areas, the Aldo Leopold Wilderness, Blue Range Wilderness, and Gila Wilderness. The 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 is also the world's first designated wilderness, 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.

In addition to designated wilderness areas, the Gila has two Wilderness Study Areas, Hell Hole WSA and Lower San Francisco WSA, which are managed to retain their wilderness character until Congress acts to either designate as wilderness or release from wilderness study.

Wilderness Ethics

In wilderness there are no roads; the only travel permitted is by foot or horseback. You will find no logging, resorts nor commercial uses of any kind except grazing. Hunting and fishing, however, are open to all citizens under New Mexico game laws.

Please follow these simple points to maintain our wilderness:

  • Motorized vehicles are not permitted in the wilderness.
  • Mechanized equipment (including mountain bikes) may not be used in the wilderness.
  • Leave no trace of your visit.
  • Check with the local land management agency for trail information and other considerations.

Leave No Trace

The 7 Principles of Leave No Trace provide an easily understood framework of minimum impact practices for anyone visiting the outdoors. The Principles can be applied anywhere — from remote wilderness areas, to local parks and even in your backyard. Each Principle covers a specific topic and provides detailed information to empower you to minimize your impacts. The 7 Principles are well-established and widely known but not static. Leave No Trace continually examines, evaluates, and reshapes the Principles and conducts research to ensure that they are up to date with the latest insights from biologists, land managers, and other leaders in outdoor education.
