The loop at the end is ridden counter-clockwise only.
From the backside of Blueberry Loop, follow this trail down a steep sandy/loamy hill (be mindful of roots). Immediately reach the bottom of the saddle and use your speed to reach the plateau and follow the arrows counter-clockwise. There are some small berms you can pop off of with enough speed just for fun. Follow around and drop back into the saddle before returning back to the Blueberry Loop.
