Heading north to south you have absolutely fantastic flowing singletrack following contours around a long valley. There is some exposure, so you'll want to be careful of possible falls on steep side slopes. The exposure might test the mental ability of newer riders, though it is scenic and not overly difficult.
Then a short, tough climb leading to the crest of the ridge. Stop here and hike up 50 meters for a fantastic view. Then there is a fast descent down to Zapotal Valley. Rides great in the other direction too. The climb is longish, but not so hard.
