Grafton Mesa Trail Professional Review and Guide
"This short spur leads off from Smithsonian Butte Trail and runs out onto Grafton Mesa. The small trail is rocky and narrow, and the first part runs through the juniper and cedar trees that dot the top of the mesa. When the trees abate, there are wide-ranging views over the eroded Pastry Ridge, so named because of its resemblance to pie crust.
The trail gradually descends, passing short spurs, one of which leads to a large pleasant campsite at an oil drilling post with views over Zion National Park. Special Attractions: Views of Pastry Ridge and Mount Kinesava; Accesses historic hiking trail into Grafton ghost town. High-clearance 4WDs are preferred, but any high-clearance vehicle is acceptable. Expect a rough road surface; mud and sand are possible but will be easily passable. You may encounter rocks up to 6 inches in diameter, a loose road surface, and shelf roads, though these will be wide enough for passing or will have adequate pull-offs."
