Steep, technical, fast and fun. An excellent trail built specifically for mountain biking.

djn Nechrony


This trail is a directional downhill trail. Ride up HyMasa Trail or the Amasa Back road to access the top end start.


This is an outstanding new singletrack along the rim below the iconic Amasa Back 4x4 trail. It's a very well built, thoughtful and challenging trail.

The top end starts with an easy climb that continues from HyMasa Trail. The views of Jackson Hole and Canyonlands are outstanding.

A big rock drop will mark the start of the descent. The upper half of the trail is designed for longer travel bikes and riders who enjoy technical descending. There are plenty of options to avoid most of the larger drops, so you can make it as hard as you want. After the first series of descents and rollouts, Captain Ahab contours a bit with some short punchy climbs and drops.

The lower half of the route drops into tight singletrack nesteled above Kane Creek. This part of the route is fast and exciting with some exposure along the cliff edges. It's has good flow and very little in the way of climbing.

The final stretch of Captain Ahab drops down through a spicy rock garden before rolling out to the Amasa Back / Cliffhanger road.

*Note: If you're looking for a shorter route or want to avoid the more technical upper sections, there is a bypass at 3.3 miles into the HyMasa Trail climb.

Fun descent but short. I'm used to 5000' descents in the PNW, unbroken by any pedaling, so maybe I'm spoiled.

Make sure to follow the paint at the drops to hit the well placed rocks. Ahab was a lot of fun. No need for a downhill bike. Sep 18, 2015
This may be my favorite trail ever. Gotta keep your mind sharp! Lots of chunky fun! I agree, an AM bike would be better than a DH bike because there is some climbing, but a DH bike would be lots of fun, too. Aug 31, 2016
