This 230-acre glacial outwash basin, located in the southwest part of the island, is considered the birthplace of conservation on Block Island. Walk down Black Rock Road off of Cooneymus Road. About 0.25 miles down on your left, you will see a wooden gate and turnstile marking the trail entrance. Bear left, where the trail splits to traverse the bottom of the Hollow (where you can also access a trail leading to Fresh Pond); bear right to ascend a knoll with a wonderful panoramic vista. The trails intersect again to return to Black Rock Road. If you turn left and continue down the road, you can access the beach via a trail down the bluff.
Directions: Turn onto Walk down off of Cooneymus Road. About 0.25 miles down on the left there is a turnstile at the head of the trail. The trail soon splits. Bear left to traverse the bottom of the Hollow; walk right to ascend a hill with a giant vista.

Coastal grasslands set on the bluffs above the Atlantic provide habitat for raptors and passerines. Walk from entry on south side of Cooneymus Road near West Side Road intersection.

The Clay Head Preserve traverses some of the most spectacular scenery on the eastern seaboard. The trail runs east toward the ocean about one-third of a mile. Soon you will reach an intersection in the trail. If you turn right, you will end up on the beach. Turn left and the trail winds up above the clay bluffs for which this area was named. At the top of the incline, follow the trail along the bluff. Periodically you will see trails on your left heading away from the ocean; this part of Clay Head is known as the maze. These intertwining trails are unmarked and are perfect for hours of wandering when you want to enjoy the outdoors.
Directions: Look for a post marker on the right side of Corn Neck Road about two miles from town. Turn right down the dirt road and drive about one-third mile to a parking area and see the Clay Head sign.
