The massive stone bridge arch - the largest marble cave entrance in the east - dominates this spectacular display of Adirondack geology and has captivated visitors for over 200 years. Unlike slow forming limestone caverns, these marble caves were rapidly formed during the last ice age by an unusual fault exposing a layer of ancient marble to raging acidic floodwaters from melting glaciers.
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. Try the “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”.
After exploring the caves, relax in a large family swing or enjoy homemade fudge in wooded picnic areas. See the 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 and 8 diamond saws/3 rock poppers 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 Climbing Wall, Frisbee Golf Course, fish feeding, jewelry making, Dino Digs & Butterfly Box.
