Mossy Rock trail starts just up the trail on the left side. After a short climb, the trail descends through several steep rocky sections. Mossy Rock then makes a big sweep to the right and climbs up a little, flattens, and then drops back down through more technical rocks. The lines through this section are hard to see, but the trail has been built like a chute in order to keep you going the right direction.
The trail pops out onto the gravel road where you can climb, left, back to the parking area to try again, or you can go right and look for Backside Trail
