The longer hiking trails at the Island generally begin on the mesa top and descend via switchbacks to the White Rim bench. A few trails continue down to one of the rivers. Most are considered strenuous, with an elevation change of 1,000-2,000 feet, and require negotiating steep slopes of loose rock as well as sections of deep sand. Water is scarce in most areas. Trails are marked with cairns (small rock piles).
Length: 8.3 mi/13.3 km round-trip
Start: Upheaval Dome Trailhead
This strenuous backcountry route follows the washes on either side of Upheaval Dome. Spur trails partway around the loop provide access to the center of the crater (3 mi/4.8 km) and the Green River (7 mi/11.2 km.) Total elevation change is roughly 1,300 feet. The north side of the loop passes through a riparian area where water and shade are usually available. There is one designated campsite along the trail.
