From your parking spot, run back on the pavement the way that you drove in for a few hundred yards, passing a small metal storage building on the right. Turn right here into a small field, go between two fence posts, and continue to bear right on the edge of a larger field. Run a few hundred yards, looking for a sharp right onto singletrack into the evergreens. This is The Pines section.
Following the blazes through The Pines, you'll come back toward where you parked, and then you'll take a sharp left up the hill along a split rail fence. Continue to follow the blue diamonds uphill through a grassy area with large trees (and the pavilion to the right), dip back into the woods as you continue to climb toward Roundabout.
