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.
About an hour drive from Troy, Howe Caverns provides visitors with a sense of caving or spelunking, without needing the advanced equipment and training usually associated with such adventures. Howe Caverns is the second most visited natural attraction in New York State, after Niagara Falls.
