Upper Muley Twist Canyon cuts lengthwise along the spine of the Waterpocket Fold creating a colorful, meandering canyon. The Navajo and Wingate sandstone layers are exposed here, tilted by the uplift and folding of the Earth's crust and sculpted by millions of years of erosion. The Wingate, stripped of its protective Kayenta cap rock, has eroded into unusual forms including many large arches. The 0.9-mile (1.4 km) round-trip hike to Strike Valley Overlook provides outstanding views of the Waterpocket Fold and the surrounding area. The rim route in Upper Muley Twist Canyon provides similar views.
Highlights of the hike are narrow canyons, expanses of slickrock, large arches, and dramatic vistas from the top of the Waterpocket Fold. The route is marked with rock cairns and signs, but carrying a topographic map is recommended. It is extremely hot in summer and water sources are unreliable; carry adequate water. Use caution in narrow canyons, particularly during the flash flood season (typically July-September). Free backcountry permits are required for all overnight trips and can be obtained at the visitor center.
This route is not an official, maintained trail. Route conditions, including obstacles in canyons, change frequently due to weather, flash floods, rockfall, and other hazards. Routefinding, navigation, and map-reading skills are critical. Do not rely solely on unofficial route markers (rock cairns, etc.); they are not maintained by the National Park Service (NPS), may not indicate the route in this description, or may be absent.
