The Potash Road merges into the famous mountain bike route, the White Rim Trail, but only for a heart pumping four-mile climb out of the canyon. After six paved miles, rocky Long Canyon Road drops abruptly back to the river.
Route location: In Grand and San Jaun counties in Utah, southwest of Moab. Cuts through sections of Canyonlands National Park and Dead Horse Point State Park.
Surface: Gravel bedrock roads and about 6 miles of paved state highway.
Distance: 33.8 miles.
Ride time: Allow 3-4 hours for the loop.
Difficulty: Moderate to difficult. There is a very steep four-mile climb out of the canyon on the Shafer Trail and a fast rocky descent through Long Canyon.
Directions: From Denver, travel west on I-70 into Utah and south on U.S. 191. Turn right on County 279 for 13.5 miles. Park on the right at the bottom of Long Canyon Road.
