The Barracks Trail Professional Review and Guide
"This short spur trail leads from Elephant Butte Trail to an overlook of the East Fork Virgin River. The trail is sandy and ungraded, and it winds through scattered vegetation. After 3.3 miles, there is a spectacular, shaded campsite on the edge of the cliff, with views over Zion National Park and the White Cliffs.
Special Attractions: Views of Zion National Park and the White Cliffs; Overlook of the Virgin River; Fun, sandy trail. High-clearance 4WDs are recommended, though most stock SUVs are acceptable. Expect a rough road surface with rocks larger than 6 inches, but there will be a reasonable driving line available. Patches of mud are possible but can be readily negotiated; sand may be deep and require lower tire pressures. There may be stream crossings up to 12 inches deep, substantial sections of single-lane shelf road, moderate grades, and sections of moderately loose road surface."
