The Circle O trail is an excellent addition to Moab's selection of rides, new in 2007. The trail is 100% slickrock, on top of Entrada sandstone. The Circle O trail itself is only about 3.5 miles long with only 200 feet absolute elevation change. But to get there, you need to ride part of the Bar M trail , so the shortest total ride that includes the Circle O will be about 10 miles. This trail is one of the " Moab Brand Trails ".
Advanced riders may ride counterclockwise on Bar M, riding the Bar B Loop, then Circle A to the slickrock portion of Circle O. Completing the remainder of Bar M, this ride is 12.5 miles. The up-and-down sandstone makes this route a bit of work.
The trail is constant motion. Up and down, circling around. The trail is marked by a narrow strip of concrete stain on the rock. It's not perfect, but it's fairly straightforward navigation.
