The massive Stone Bridge is the LARGEST marble cave entrance in the eastern U.S. and is still being carved by the beautiful Trout Brook.

In summer, walk the self-guided and above-ground nature trail to witness this spectacular display of ancient Adirondack geology. Our rustic stone-step and gravel trail features the old Sawmill Site Waterfalls, Artists’ Gorge, incredible potholes and of course several surface caves. Descend into lighted caves and grottos with raging water or tranquil dark pools. For the more adventurous spirit, sign up for a guided summer Adventure Tour; a 3-4 hour spelunking cave crawl including a cave float!

In winter, witness a magnificent transformation of landscape as ice flows form everchanging sculptures beneath the Stone Bridge and along the river. Snowshoe through the woods and return to toast marshmallows by the bonfire. Disc golfers can even play our beginner’s course in winter, if they’re hardy enough!
