The trail is a lollipop loop with two short stems.  One stem begins at the high point of the preserve, 0.1 mile from the Willow Drive parking lot at the junction with the blue trail.   An easier access is to follow the wide trail from parking lot downhill for 0.1 mile to junction with yellow trail (to right, uphill in 0.1 mile is blue junction at rocky knob).  The trail turns left downhill and in 0.1 mile crosses a rickety bridge over a stream, then ascends to begin the loop–to the left, the trail ascends gradually and in 0.1 mile it curves around to the right (straight ahead, an unmarked trail leads in 300 feet to  Highlands Ridge Park and its trail system).   After looping to right, the trails passes through a “green tunnel” across a regrown field.   It crosses a small bridge over a seasonal  stream and at 0.5 mile widens out on a broad woods road and then reaches a junction–to the right the trail descends to beginning of loop at 0.7 mile.    Going straight on the woods road, the trail turns left as the broad woods road turns right to begin the blue trail.   Crossing a tiny tributary, the trail becomes a woods road and at 250′ crosses Ayers Brook on a wooden bridge, ending at the junction with the red trail.
