The re-re-routed Jessup Trail (yellow blazes) starts opposite the parking area (which is also where the hike ends).

About three miles from where you last left the Jessup trail turn left to (again) go onto the Jessup Trail (there may be both yellow and blue blazes but it is the yellow blazes that indicates the Jessup trail). Just beyond the peak (1664') white marks on the rocks will point west to the Megaliths (to the left). Follow the white arrows and small white squares where they lead you to.

A short while after returning to the Jessup trail and continuing north (the direction you had been going), you will intersect the black dot on white blazed Dark Hollow trail. Stay on the Jessup trail. Turn right onto the Sweet Clover trail (white blazes, this turn is not well marked!). The trail emerges besides railroad tracks (fast trains run here throughout the day!). Go across the tracks and and continue on the Sweet Clover trail. While staying on the Sweet Clover trail, make a left onto the (second) dirt road when you get to the beginning of the open field (before the highway). This will be the second dirt road you will pass after the train tracks (the first one comes soon after crossing the tracks). Take the Sweet Clover trail back to your car.

Take the George Washington Bridge to the Palisades Interstate Highway heading North. In about 19 miles exit the parkway at exit 9W onto the Thruway (Route 87/287) which heads west. About 24 miles later, exit the Thruway at exit 16.

After turning left onto Pleasant Hill Road, make the next left (onto Taylor Road) over a small bridge. Veer right at the next fork (do not turn onto Starr Road). Taylor Road crosses over the Thruway. From the initial left turn onto Pleasant Hill Road you will drive a total of about 0.35 to 0.4 miles until a small parking area ("P" in the upper right on the map below) on the right side of the road (park here, N 41.40762, W 074.08155).
