Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Grandstaff Canyon holds a perennial stream under Navajo Sandstone walls northeast of Moab off State Route 128. A maintained roughly two-mile trail (National Recreation Trail) leads to Morning Glory Natural Bridge, a long sandstone span just outside the WSA core. The canyon, trailhead, and nearby campground are named for William Grandstaff, a nineteenth-century settler in the Moab area.
Cultural sites and artifacts are protected by federal law (ARPA/NHPA) — stay on established routes, touch and remove nothing, and follow the managing agency's and the affiliated tribe's guidance on access.
