Natural Stone Bridge & Caves Park

The massive stone bridge arch - the LARGEST marble cave entrance in the east - dominates this spectacular display of Adirondack geology. Originally named Ponte de Dios (Bridge of God) by early explorers, the stone bridge has captivated visitors for over 200 years.  Jacob Van Benthuysen, Ancestor of the current owners, received the site in the 1700’s for Revolutionary War service. Guests can still visit the sawmill site he erected on the river today. This unique natural phenomenon is not only beautiful but also an extraordinarily rare feature of Adirondack Geology. Unlike the slow forming limestone caverns, these marble caves were rapidly formed during the last ice age by an unusual East-West trending fault which exposed a layer of ancient marble to raging acidic floodwaters from melting glaciers. Bring good rubber-soled enclosed walking shoes, take a walking stick, map, and camera and set out on a self-guided, ¾ mile, mostly above-ground, natural stone step nature trail and experience up-close the many unique rock features in the marble gorge, such as potholes, grottos, and mill site waterfalls. Descend into lighted surface caves with raging waterfalls or tranquil dark pools. Go at your own rate and take the opportunity to stop and enjoy the scenery at our many benches offered along the walk. The tour and map are number coded with information provided on your map. Plan on about an hour for the tour.
