Harrington Beach State Park has seven miles of hiking trails and one mile of Lake Michigan shoreline to explore. Walking the beach along Lake Michigan, hikers can see the remains of a 700-foot pier that was used in the early 1900s for shipping limestone quarried and processed at the park. The old pier is on the point which is the dividing point between the north and south beaches. Biking is allowed on the shuttle bus route from the Pucket's Pond area to the Answay Welcome Center.
