Mountain Biking Rockstacker

****   Add a review
#62 of 694 mountain bike trails in Utah
#1,299 in the world

After climbing Amasa Back there will be a jct. to the Pothole Arch trail which will take you to the start of Rockstacker. This is a very technical trail with a hike a bike entry. Only the very skilled will be able to ride it all. It can be done. I witnessed it. The "Red Line Trail" as it is refered to as by the locals, is very challenging as it rolls up and down across a slickrock bench towards Jackson's Trail. Only 1.7 miles in length, it feels so much more.

    Two pretty legit technical spots, they get the adrenaline flowing. Both ride-able, and very fun. Outside of that, nothing super special, you kind of climb out of it a ways to get back to the main network, and adds some miles onto Amasa Back.

    Okay, this trail is insanely technical. Starting from Pothole Arch, Rockstacker dives off the mesa onto some off-camber rock and sand section. As it wraps around the mesa you will continue to ride/hike over large ledges and switchbacks, the majority of which is probably unrideable for most. Once past that, it gets pretty fast and furious over slickrock and singletrack.

    I think I went the wrong way on this trail (I'd recommend coming from Pothole Arch towards Jackson's), but either way you go there are going to be some absolutely massive features to conquer! The only difference is, will you be attempting to ride down them, or will you be scrambling up them? Of all the trails that I've ridden in Moab so far, Rockstacker is the closest to a true double black.

    Rockstacker is a very technical singletrack off the Amasa Back mesa. Awesome views along the Colorado River abound as you roll up and down over a slickrock bench towards Jackson's Trail. A red line has been generously distributed along the way to keep riders on the intended route. Can be easy to venture off route so BE CAREFUL! Just under 2 miles and connects to Jackson's singletrack. Advanced to Experts will love it as novice to intermediate riders will struggle.
