June 13, 2025, Slickrock Trailhead

The Slickrock Trail is a popular trail for mountain bikers. While not suitable for road bikes, the trailhead has parking, picnic tables, and restrooms, so it is a good place to start a ride or for a mid-ride bathroom break.

Stay off your bike when the 2 signs request to do it and enjoy a really nice technical trail after that. Itโ€™s 8 miles back to Moab, so stage your car to cut off those miles.

The views are amazing and the trail is challenging. For me the uphill sections more than the downhill sections.

A must do when in Moab and for sure the best trail if you want to convince somebody to buy an ebike. Very physical. I have the feeling the altitude is counting twice in Moab.

The elevation gain is around 400 meters with many very steep climbs. Come to the trail well prepared.

The Lower Captain Ahab Trail is an amazing, exposed, technical trail on a mix of slickrock and singletrack that leads down into Kane Creek Canyon. This is a fantastic, beautiful trail with epic views into the canyon that is also incredibly popular with mountain bikers (who often take it fairly fast) so please remain aware at all times as you run this Moab-gem!

This large pullout is the main parking area for many of the more famous mountain biking, trail running, and hiking trails including Amasa Back, Captain Ahab, and Hymasa, as well as Pritchett Canyon. Please note that overnight parking is not allowed and that this lot can fill up quite quickly during the high season, so be sure to get here early to ensure a spot!

The trailhead for the popular Grandstaff Canyon Trail, which takes you to Morning Glory Natural Bridge, begins at the mouth of Grandstaff Canyon, about 3 miles from the junction of US 191 and Highway 128. There is limited parking to be sure to get there early to ensure you get a spot!
