Except for a couple of tough spots, this trail would be rated easy. The movie "Blue" was filmed here.
This is one of my all time favorite rides in the Moab area. It has it all; singletrack, slick rock, super technical obstacles, and fast descents. There are enough easy sections to keep intermediate riders from getting frustrated, but plenty of obstacles that are tough enough to challenge the best riders.
