The Blue Range Primitive Area sits along the Arizona–New Mexico border and is the last designated primitive area in the U.S. Forest Service system, covering over 170,000 acres of canyons, steep ridges, and remote, pine-covered mountains. This area is home to black bears, elk, and wild turkeys. There are several trails that wind through its fir and spruce forests and along the Blue River, making it ideal for seasoned backpackers looking for a true wilderness experience.
