this is 3rd after porcupine and slickrock! Unique, spectacular, but it'll kick your but.

The first 3/4 mile of this trail has some very technical sections that will challenge all but the most skilled bikers. A short distance after the stream crossing the difficulty decreases and views get better. You will be challenged by sections along the way, but on the whole the difficulty remained manageable for me (limit experience and riding a bike w/o any suspension). When you near the rim the grade levels out and the riding gets much easier as you approach a viewpoint that affords a great view of a valley and fertilizer (?) plant (yech!!).

This is classic Moab riding - a strenuous climb over loose rocks, slickrock, and sand up to a spectacular view. The downhill makes it all worth it! It's pretty technical and rocky though, so if you're not comfortable with rocky dropoffs, you might be walking a lot of it. Expect it to be blazing hot in the summer - go early and carry as much water as you can.

A strenuous out & back. The start of this trail is a killer. First a steep loose downhill to the creek, the creek crossing & then the climb along ledges. But when you finally top out you'll find great views & slickrock to play on. Total mileage is 10 to ll miles with 1000 feet of climb.

Even though this is an out and back, both directions seemed completely different. Going out is a steady climb, but on my old hardtail it didn't seem so bad. It was even enjoyable for a long climb. The views throughout were great, but the views at the end were amazing! The return ride was AWESOME! Probably even more fun than Slickrock, but the climbing puts it behind Slickrock for me. I hope to head back soon with my newer Stumpjumper FSR to really enjoy the ledges and drops and rocky areas of this trail.

Detailed Trail Descriptions from Our Guidebooks

David Crowell
"The insanely steep initial descent of this locals’ favorite will test technical skills down and up, while the following climb tests willpower. An extremely technical singletrack creates a loop option. Retracing the route downhill, however, is a rocky, fast-paced frolic. Life should be full of such choices. Speaking of choices, the singletrack revival in Moab has been busy here. Dreamers cranked up a rugged four-by-four trail then explored the rock a bit and imagined wild, twisting, edge-clinging singletrack high above those that dwell below. Welcome to the dream. Rockstacker, Jackson, HyMasa, and Captain Ahab all bring flow to this rock of ages. The classic ride, described here, follows the four-by-four route called Cliff Hanger and serves as access to the singletracks described afterward."

"You'll want to watch the first 100 feet of this trail. It can ruin your ride in a hurry. The entire trail should be approached with respect. It's short, but it's a grunt with technical challenges thrown in here and there, some on the edge of a 500-foot cliff. Ledges drop into deep sand at points. It asks for speed and can surprise you as you round a corner. The ride from here can be extremely rewarding for a very experienced riders with a good sense of direction and maybe a guide. There is petroglyph panel worthy of a visit, but the riding just gets harder from this viewpoint as you climb on the very technical slickrock onto the huge sandstone monolith that is Amasa Back. Don't even think about the singletrack that goes down the backside."
