What is there to do?

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.

Need a little extra help?

The standard and adventure natural cave tours are fairly rigorous with uneven natural stone steps (over 500) and 3/4 mile long. They are not accessible with a stroller or by wheelchair (we do rent backpacks to carry the youngsters if you do not have one). However, our gift shop, PBS video, museum, rock shop and restrooms are wheelchair accessible and available free of charge.


When can we go?

Late May through June 9am to 5pm, July to early September 9am to 7pm, September through October 10a


Any top tips?

Because we keep the trail as natural as possible, please bring good rubber soled walking shoes. We do rent sneakers if you do forget your own. Much of the trail is above ground (with optional descents into the caves) and thus you are exposed to the weather. You will NOT need extra clothes to keep warm (as in other caves), but may need a rain jacket or umbrella if it rains, and bug repellent in the Spring. Bring your CAMERA.

I’m Hungry!

Food service at the main cave facility includes a snack bar with items such as: sandwiches, hamburgers, nachos and drinks. A full lunch or dinner and > 40 flavors of soft ice-cream is available at our Rt 9 Stone Bridge Café located 2.5 miles away on the corner of Rt 9 and Stone Bridge Rd. Enjoy our homemade caveman fudge. Grills and pavilions are also available for a picnic lunch or dinner.
