The views from Arizona’s Wabayuma Peak stretch all the way to California. Our recent protection of a remote 40-acre inholding brings us closer to securing the 40,000-acre Wabayuma Peak Wilderness Area from potential development.


The Trust maintains an active program of acquisitions in Arizona, having already successfully added four of five highest priority inholding acquisitions to Arizona’s designated wilderness areas, eliminating long standing access disputes, as well as existing and proposed private development.

Hells Canyon Wilderness (COMPLETED)

Yavapai County (Bureau of Land Management)

640 acres transferred

The 9,900-acre Hells Canyon Wilderness just 25 miles from Phoenix was designated in 1990. On Earth Day, 2008, The Wilderness Land Trust purchased a 640-acre inholding near the center of Hells Canyon Wilderness. The parcel included Hells Canyon itself and had belonged to a Phoenix area land developer. The area, in the Hieroglyphic Mountains, attracts rock climbers, and the canyons make for relatively easy hiking. Most of this wilderness is covered by Sonoran Desert vegetation— saguaro, paloverde, barrel cactus, ocotillo, and desert grasses. Easily accessible, primitive camping sites are plentiful.

Mt. Tipton Wilderness

Mohave County (Bureau of Land Management)

470 acres transferred


The Mount Tipton Wilderness, near Kingman, was designated in 1990 and now has a total of 31,320 acres, including the northern half of the imposing Cerbat Mountains. The 7,148-foot Mount Tipton dominates the area with views in all directions, including the Pinnacles—immense rows of maroon-colored spires towering above desert valleys. Deep washes, small valleys and bowls are found throughout the area. Large granite outcroppings break the ridgelines, the gray and red rock contrasting with the green vegetation.

Muggins Mountain Wilderness

Yuma County (Bureau of Land Management)

190 acres transferred

The 7,711-acres Muggins Mountain Wilderness was designated in 1990. Just south of Yuma Military Proving Ground stand the rugged peaks of the Muggins Mountains, a region of colorful geologic strata and scenic landforms near the California border. The most prominent summits are Muggins Peak at 1,424 feet, Klothos Temple at 1,193 feet and Long Mountain at 914 feet. Deeply cut drainages including Twin Tanks Wash and Long Mountain Wash bisect the area. A few hardy day hikers, backpackers and rock climbers make the trek here.

Swansea Wilderness

La Paz County (Bureau of Land Management)

603.59 acres transferred


A six-mile stretch of the remote Bill Williams River cuts a canyon along the edge of the 16,400-acre Swansea Wilderness. The river, rarely seen by humans, flows into Lake Havasu before the Havasu National Wildlife Refuge to create a riparian habitat. In the northern portion of the wilderness area volcanic dikes with precipitous cliffs extend from Black Mesa. There are no trails but there is hiking, rock climbing and horseback riding along the river and some side canyons.

Wabayuma Peak Wilderness

Mohave County (Bureau of Land Management)

505 acres transferred

The 40,000-acre Wabayuma Peak Wilderness in the Hualapai Mountains is a short drive from Kingman. The 7,601-foot Wabayuma Peak towers over this rocky wilderness, which plunges almost 5,000 feet in five miles to the desert floor. Sonoran and Mojave vegetations include the northernmost stands of saguaro cacti. Above the desert, chaparral and piñon-juniper woodlands thrive, as do ponderosa pine and Gambel oak. This is fine country for year-round backpacking and horse packing trips.
