Leaving the three way intersection behind the trail heads east following the contour of the lake. This section is perhaps the most fun but also one of the most technical. It is heavily wooded with several steep and eroded climbs and descents. This section climbs and descends ridges and follows ridge lines through the trees. About halfway through this section it turns north at the top of a ridge. It continues north for some distance through the trees until it descends out into the open. Here it will turn to the east toward the water, coming within several feet of the water line before turning north. At this point you will traverse a gated fence and continue north along the treeline until the trail takes you east through another clearing. After this clearing you will head up a rocky and eroded climb until you reach a fence, you will follow this fence to the east until it turns southeast and you descend to a gravel road.
