Block Island (11 sq. mi.), crisscrossed by more than 20 miles of trails, is nearly impossible to get lost on and offers some of the Easts most spectacular seashore and birdwatching. A great day hike, the Clay Head Trail zigzags an 11-mile course around the northern half of the island, or take a shorter section that leads you straight to the best birding action on the northernmost bluffs. From there you can navigate a confusion of unmarked inland trails throughout the ten-square-mile island.
Ferry service runs from Point Judith, Providence, and Newport, Rhode Island; Montauk Point, New York; and New London, Connecticut. Call 401-783-4613. Expect a one- to three-hour trip from dock to dock. On Block Island, pick up the trailhead on Corn Neck Road.
Overall, Block Island is the 1st most popular hiking trail of all 3 hikes in Rhode Island.
