Northwest of Moab, the Seven Mile Canyon Trail is a 4.5 hour horseback ride through a sandy wash.
Directions to the Trail: Go North from Moab on Hwy 191, nine miles out of Moab. Turn west onto Hwy 313, and park at the fourth possible left turn. You will park on a flat area next to the road, and there is plenty of room to turn around. (If you start to climb a hill on Hwy 313 you have gone to far). Ride down the dirt road and follow the canyon to the south.
Trail: Follow the jeep route up the wash. Stay in the main canyon. Side canyons are impassable, and impossible to ride. At the end of the canyon is a grotto, which is usually has a pond. The water is not for human consumption.
Overall, Seven Mile Canyon Trail is the 20th most popular horse trail of all 25 horseback rides in Utah.
