The 7,880-acre Mount Trumbull Wilderness sits on the Uinkaret Plateau in Grand Canyon-Parashant National Monument. From the vault-toilet trailhead on Mohave County Road 5, a marked trail climbs about 5 miles round trip through pinyon-juniper and aspen to the basalt-capped summit, with views across Toroweap Valley and the Grand Canyon. Access is a long dirt-road drive from St. George or Colorado City.
