Captain Ahab

Captain Ahab is a one-way trail in the Amasa Back riding area . It must be reached via the Amasa Back or Hymasa trails. This singletrack requires good technical skills, confidence, and strength. It's a great ride, but it's not a cruiser. It was designed as an expert-level singletrack. 

General Information:
The singletrack is 4.3 miles in length. While it's one-way, it's not really a "DH" downhill trail. From the ridgeline 2.7 miles up Amasa Back it will descend 300 feet in elevation, but up-and-down riding tallies almost 1000 vertical feet of climbing over the course of the trail.
There are great views all along the way, and fabulous-forever views at the top. Add those views to the riding, and every rider I've talked to absolutely loves Captain Ahab.

Just getting started on Amasa Back. This is your view as your bike hits the heavy sand above the creek. Go for the rock pile, but you won't make it.

We're a mile up Amasa. This is the return path from Captain Ahab.

A ride directly up Amasa to Captain Ahab and looping back will be 8 miles and 1800 vertical feet of climbing. Alternate: climb via the new Hymasa singletrack.

I'll also describe an Epic Tour of Amasa for 17 miles and 3000 vertical feet. This is a monster ride, hitting all of Amasa, Pothole Arch, Rockstacker, and Captain Ahab.

There's also the option of cutting Captain Ahab in half by using the midway connector. Take the connector at Amasa mile 2.3, ride 1/2 mile to Ahab and turn left. This will visit the lower half of Captain Ahab, which is almost purely downhill. The ride will be 5.9 miles, with 700 vertical feet of climbing. If you have a heavy DH rig, this is your path.

View on the connector trail. It's 1/2 mile on this trail between the midpoint of Ahab and Amasa.
You can also use the connector to bail out after doing upper Ahab. While you've already done most of the heavy lifting, the connector plus lower Amasa is technically much easier and will go faster. Use this route if you've broken down (bike or body) or run out of time.
The Ride!
Navigation for the short loop is straight-forward. Ride the Amasa Back trail 2.7 miles to the ridgeline, fork left on Captain Ahab, and follow it back to Amasa.

Lay of the land. We're on Amasa looking back at the ridgeline where Ahab starts, from about 1/2 mile further uphill. Ahab will go past the spire on the left and climb along the row of cliffs (toward the right in the photo).
From the Amasa Back parking, pedal uphill on gravel road 0.6 miles. At the sign, drop right over a series of ugly rock stairs. The smoothest line is: far right, then cross over in the middle of the steps to far left.
At the bottom is a big drop. There's a sneaker route on the far right.
Most bikes now keep left, while 4x4s go down to the right. The paths rejoin just before the creek. Splash through and bog down in the sand. There's a mean ledge up ahead, but you'll never keep enough momentum to clean it.

The trail is marked with blue stripes on slickrock areas. This is early in the ride on a smooth section.
Amasa is series of ugly tough ledges spaced between stretches of ugly tough climbing. It's Not My Favorite Moab Trail. But then I'm a old crybaby with lots of slow-twitch fibers, and you're a biking god. Climb that hill.

Captain Ahab - Technical Amazingness

[Back to video list ]
At mile 1.0, turn to the right as the bottom of Ahab joins on your left. Do Not Enter. Captain Ahab is one-way, and for good reason.
At mile 2.3, keep right as the connector to Ahab's midpoint veers off on your left. Or go left if you're looking for the short-short version of the ride.

This trail has seen a lot of work to create countless rock ramps. Approaching what looks like a 10-foot cliff, we spot a rock ramp at the last second.
At mile 2.7, Amasa crests a ridge. Most riders stop here to take in the view. To do the short loop, immediately fork left onto the singletrack of Captain Ahab. (For the epic ride, continue on Amasa.) About 100 yards west on Ahab, Hymasa joins on your left. Keep right.
Shortly after entering Ahab, you'll realize you've got climbing to do. The trail follows the anticline uphill to the same elevation as the Amasa viewpoint. Over 1/2 mile, you'll gain 200 feet of elevation, but you'll climb two or three feet for every foot you keep.

There are constant turns and up-and-downs. Flat sections are rare and very short. The bike bucks up and down constantly. But there isn't anything as technically difficult as the ledges on Amasa.

Plan to bring fresh legs and an aggressive attitude. If you want cruising on similar sandstone, try Bull Run and Little Canyon . This trail seems designed to serve up fun challenges. Don't plan to mosey along with your butt on the seat.

Once you're finally heading downhill, you'll still be cranking uphill frequently. As you approach the midpoint, you'll be maintaining some flow and speed.

Rock ramps are everywhere. The trailbuilders seem to take the toughest line, then place rocks so you can get there.

The bottom half of Captain Ahab flows better. There are longer sight-lines and the course of the trail feels more intuitive. But there will still be some stiff little uphills, so you're not through working yet.
As you enter the gorge, you'll see why this is a one-way trail. There are quick up-and-downs as you hug a band of tilted rock midway down the cliff. It's advanced, but not extreme, technical.
At mile 7.0, you'll rejoin Amasa. Want another loop?

The Epic Amasa Figure-Eight Ride:
The Epic Tour of Amasa is harder than it sounds. You'll already be tired when you hit the climbing on Captain Ahab.

The ride is a figure-eight with a couple of loose threads. Take Amasa to the viewpoint and back to the Pothole Arch trail. (The little out-and-back is a "loose thread" on the figure-eight.) Take Pothole Arch out to its viewpoint and back to Rockstacker . (Another loose thread.)

Take Rockstacker to the Jackson ST connector, but cross the ridge to Amasa. (Don't go down Jackson!) Ride a mile to Captain Ahab. Finish with Captain Ahab back to Amasa. It's 16.5 miles with 3000 vertical feet of climbing.

Getting there:
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, and head uphill about 2/3 mile. 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.
