Natural Stone Bridge & Caves

The massive stone bridge arch - the largest marble cave entrance in the east - dominates this spectacular display of ancient Adirondack geology from rock over one billion years old. Take a walking stick, map, and camera and set out on a self-guided, above-ground, natural stone step nature trail and experience up-close the many unique rock features, such as potholes, grottos, a gorge and mill site waterfalls. Descend into lighted surface caves with raging waterfalls or tranquil dark pools. To learn more, see the Adirondack memories display or view a free PBS video describing the history and geology of the caves.
