Amasa Back Riding Area

Amassa Back Trail Map

Location: Head south on Moab's Main Street. When you reach the McDonald's on your right, turn right onto Kane Creek Blvd. After 0.6 miles, go straight where the road seems to turn right (500 West). Drive along the Colorado River about 5 miles until the road turns to gravel. Ignore the trailhead and payment signs. You're not there yet. Pass the lower (free) Kane Creek parking area at the mouth of the canyon. Head uphill with towering cliffs to your left and a steep drop-off on your left. Go about 2/3 mile from the mouth of the canyon. Watch for the "Amasa Back Parking" area at GPS N 38 31.329' W 109 35.501'. Park here. Pedal further up the gravel road 1/2 mile, and turn right onto the trail at the sign. Descend the rock steps. All trails in the area are reached via Amasa Back.

Amasa Back

Ten mile out-and-back crosses tough ledges both uphill and down. Recommended for strong, skilled, and conditioned riders only. Absolute altitude change 1050 feet (3900 base elevation), 1300 climbing. Must cover at least the first 2.7 miles of this route to reach any other trail in the system.

Pothole Arch

The Pothole Arch trail forks off Amasa back at mile 4.6, just before the last little climb. Rolling ride with great views. Good as an out-and-back two miles each way, or to connect to Rockstacker.

Rockstacker is a 1.7 mile slickrock ride along the cliffs above the Colorado, on the north side of the peninsula. Rockstacker forks off Pothole Arch at mile 1.1 from Amasa (5.7 miles from the bottom, 6.5 miles into the ride if you've gone out-and-back to the Amasa viewpoint). If you've done all of Amasa, backtracked and done all of Pothole Arch, then backtracked to the trail fork, you'll be at mile 8.3.

Jackson Singletrack

Jackson ST descends on cliffs above the Colorado from the end of Rockstacker down to the Kane Creek road at the mouth of the canyon. There are many tricky spots and some potentially deadly cliff exposures.

Captain Ahab

Captain Ahab is a one-way singletrack that forks off Amasa at the first ridgeline (mile 2.7 after 700 vertical feet of climbing).  It climbs another 300 vertical then descends 4 miles over very technical terrain. There's a mid-point connector to bail out, or to make a shorter loop. The train rejoins Amasa just above Kane Creek.

Hymasa is a two-way trail that substitutes for the main Amasa jeep road for the main climb of descent. It's upper-intermediate technical, the easiest trail in the Amasa riding area.
