John Boyd Thacher State Park, is situated along the Helderberg Escarpment, one of the richest fossil-bearing formations in the world. Even as it safeguards six miles of limestone cliff-face, rock-strewn slopes, woodland and open fields, the park provides a marvelous panorama of the Hudson-Mohawk Valleys and the Adirondack and Green Mountains. The park has volleyball courts, playgrounds, ball fields and numerous picnic areas with nine reservable shelters. Interpretive programs are offered year-round, including guided tours of the famous Indian Ladder Trail. There are over 25 additional miles of trails for summer hiking and mountain biking, and winter cross-country skiing, snowshoeing, hiking, and snowmobiling.
