The United States Congress designated the Mount Trumbull Wilderness (map) in 1984 and it now has a total of 7,880 acres. All of this wilderness is located in Arizona and is managed by the Bureau of Land Management.


Just north of the Grand Canyon and Mount Logan Wilderness, located at the southern end of the Uinkaret Plateau, Mount Trumbull is a large, basalt-capped mesa rising to 8,028 feet. Steep south and west slopes are dominated by piƱon and juniper with cliff rose, manzanita, silktassel, and shrub live oak. You may see groves of aspen and Gambel oak with big sage, agave, and cactus lower down. On top of this plateau is a pristine forest of ponderosa pine that has never felt the logger's saw.

Mule deer, Kaibab squirrels, coyotes, bobcats, mountain lions, jackrabbits, skunks, porcupines, big brown bats, and other smaller mammals inhabit the area. Wild turkeys, hawks, owls, and other birds are abundant. Close to the ground many lizards, skinks, and snakes slither and scamper, among them the western diamondback rattler.

The Mount Trumbull Trail climbs about five miles round-trip to the summit. The trail fades out as you near the top, so bring a map and compass to reach the northern rim of the mountain where you will see superb views of the region to the north, west and east as far away as 90 miles. Not far from the base of the mountain at Nixon Flat and near the Mt. Trumbull Trailhead, potable water is usually available. Primitive camping is available at any previously disturbed area near the maintained dirt roads.
