Start at the sign, on the South Road, marking the Chilmark – West Tisbury town line; proceed up-Island 0.5 miles. Turn left here onto the Quansoo Road (it is unmarked). Travel 1.4 miles down the Quansoo Road but be careful to stay left at both the 0.5 mile fork (Quenames Road) and the 1.1 mile fork (Black Point Road). The first of two trailheads is located here; it is open year-round and is adjacent to a set of green gate posts. A second trailhead, open from October 1 to May 31, is on the left 0.7 miles farther down the Quansoo Road (be sure to turn right 0.2 miles after the green gate posts).
