Just under 10 minutes down the white blazed trail, the trail climbs a ridge and passes right next to a 100 foot wide X 15 tall wall on the left, of really nice, high quality stone, with horizontal cracks and small roofs. It should provide some easy traverses and straight up problems.
Follow the white trail from the end of the spur road as it drops off to the left from the high ridge with the pavillion. The trail will cross 3 shallow streams, passing the Great Wall on the left. The Long Wall is right next to the trial as it heads up another ridge.
