Rockin A Trail
One of the Moab Brand Trails
Seven miles north of Moab, the Moab Brand Trails offer a wide variety of biking fun. The Rockin A trail is a short technical section, only 1.8 miles long. However, the up-and-down quick-turn type of riding makes it a fair amount of work. This trail connects the southern end of the Bar M Loop and the Bar B Loop to the Circle O trail.
The shortest ride that includes the Rockin A trail is 8.7 miles. This is a counterclockwise trip around the Bar M, skipping a one-mile portion of Bar M to ride the Rockin A.
Rockin A is significantly more technically than Circle O. But it's half as long. So if you're trying to choose one over the other, Circle O will be more satisfying for an early-intermediate rider.
Rockin A is uphill -- and a harder ride -- in the north-to-south clockwise direction. My video shows it clockwise, but most riders prefer to ride from south to north. This puts Rockin A slightly downhill in the toughest sections.
Hard-core bikers will ride Bar M to the Bar B trail (right across from the Rockin A's start), then ride the Bar B loop before entering Rockin A.
After completing Rockin A, ride Circle O before completing your loop. Or, head back to Bar B and drop down Killer B.
The ride is 100% slickrock. The Entrada sandstone forms waves, so you'll be constantly making short climbs and descents. There are a couple of ledges and wheel-traps that require either technical skill or a dismount. There's no cliff exposure or other truly hairy stuff.

From the north: Drive south on US-191 for 22 miles south of I-70. From Moab, drive 7 miles north from the Colorado River on 191. When you see the Gemini Bridges parking area, look for a gravel road on the opposite side (east, away from the cliffs). Turn onto the gravel road and immediately go right, then right again into the parking area. GPS N 38° 39.38' W 109° 40.66'. The trail starts by riding the gravel road either north or south. Our ride description assumes you'll ride south out of the parking lot, counterclockwise on the Bar M.
