Lower Muley Twist Canyon

Lower Muley Twist Canyon is a 5.9-mile point-to-point backcountry hike from the top of the Burr Trail switchbacks to The Post, dropping through the canyon before climbing east over the Waterpocket Fold on the Post Cutoff. It is not a maintained park trail. I’d choose it if you’re comfortable navigating remote terrain and can arrange a shuttle. Without a second vehicle, turn around at the cutoff; that makes a 7.6-mile round trip. Allow about five hours for the full crossing, with more time if you stop often or take the exposed climb slowly.

The route drops quickly from the Burr Trail trailhead, and a short narrows section appears about two miles in. The east wall is white Navajo Sandstone streaked with black desert varnish; rust-colored Wingate and Kayenta layers add a second palette. Large alcoves open along the canyon. These are real canyon miles, not a quick walk to a viewpoint.

At 3.8 miles, the signed Post Cutoff leaves the canyon and climbs east toward The Post. This 2.1-mile section crosses steep slickrock with loose footing and several exposed places, including a particularly exposed 100-foot stretch. The climb earns broad views across the Fold, but it is the route’s serious crux; wet or icy rock makes it especially hazardous.

From 1881 to 1884, the canyon served as a wagon route for Mormon pioneers traveling toward San Juan County. Its name comes from the narrow passage, once thought tight enough to “twist a mule.” The best season is spring or fall. Water sources are unreliable, summer heat is extreme, and flash floods can make narrow canyons dangerous. Route markers can be absent or change, so carry a topographic map and know how to navigate it. Pets are not allowed on the route; an overnight stay requires a free backcountry permit.
