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 explorers and later described in Morse’s Geography of 1790, the stone bridge has captivated visitors for over 200 years. Unlike the slow forming limestone caverns, these marble caves were rapidly formed during the last ice age (10-13,000 years ago) by an unusual East-West trending fault which exposed a layer of ancient marble (over 1 billion years old) to raging acidic floodwaters from melting glaciers. Baby caves made from ancient rock.
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 in the marble gorge, such as potholes, grottos, and mill site waterfalls. Descend into lighted surface caves with raging waterfalls or tranquil dark pools. Cavers are currently completing a survey of the cave systems and the owners have developed an “adventure tour” to explore additional caves for those willing to crawl and get a bit dirty – only to get rinsed off with the final “cave float”.
The property continues to be managed by relatives of Jacob Van Benthuysen who received the site in the 1700's for Revolutionary War service. Every year, new hands-on activities are added to enhance the park and educational experience. After exploring the caves, relax in one of our large family swings or enjoy homemade fudge in our wooded picnic areas. To learn more, see our Adirondack memories display or view a free PBS video describing the history and geology of the caves.
An extensive Rock Shop offers many fine crystals, gems, fossils and bookends. In addition, 8 diamond saws and 3 rock poppers are available to open Mexican geodes, each one a treasure with agate designs or crystals. Other activities and fun for the kids include: Gemstone Mining, Gold Rush Mine, Crystal Quest Mine, Caveman Challenge Bouldering Wall, 18 hole Stone Bridge Disc Golf Course, fish feeding, jewelry making, decorating walking sticks or uncovering ancient bones in our Dino Dig and our new Butterfly Box Display. Food service includes a snack bar with sandwiches and drinks at the caves facility and > 40 flavors of soft ice-cream at our Rt 9 Stone Bridge Ice Cream Stand and Artisan Gallery. Grills and pavilions are also available. The facilities are a great site for birthday parties or corporate events (inquire for special pricing or after hours availability). Cabins are also available for rent.
Now open during the winter for Snowshoe Trails, including views of the massive Stone Bridge entrance, frozen waterfalls, sinkholes, Trout Brook and many scenic summit views. Over 12 miles of trails and soon some to be converted to cross country trails.
