step back in time
as you walk our nature trails in the midst of a primeval Adirondack Forest. Stroll past Rainbow Falls, Elephant's Head, Column Rock, Hyde's Cave and the eerie quiet of Mystic Gorge. Descend hundreds of feet to walk on natural stone walkways and gaze upon eons of geologic history etched in stone.

Experience our most popular offering, the Classic Tour, by adding a scenic raft ride and float the legendary waters of the Ausable River through a maze of breathtaking rock formations sculpted over thousands of years by the river's currents.

              Open Year Round

Come for a hike & explore the Grand Canyon of the Adirondacks! All Trails, including the popular Inner Sanctum and Rim Trails are OPEN!  They are self-guided (basic admission) thanks to the hard work of the trail crew who have been successfully keeping the ice from dangerous buildup on the lower trails.

If you aren't comfortable on your own in winter, or would like a more indepth experience, guided hikes are available with a reservation.  The Winter Tours are truly stunning and provide access to the depths of the chasm where 150' icicles that stretch from rim to river cover the chasm walls.  Appropriate winter equipment required: snow shoes and/or ice cleats (rentals available). 

The Adventure Trail and Adventure Tours are also available.  Float tours are closed for the season and will reopen next May.  

New this year to the chasm is Rock Climbing for those who prefer a little more excitement.  Experienced guides take guests up chasm walls  jutting right out from the river,  an experience that will surely get the blood pumping! Available by reservation only.


The cafe, located in the welcome center, is closed for the season.  Please feel free to bring your own lunch.  Snacks are available.  The gift shop is open.

The new Ausable Chasm Museum is also open.  This new museum features exhibits and photographs by Seneca Ray Stoddard (1844-1917), nostalgic souvenirs, and displays of extreme natural events that have devastated the chasm over the years. 


The campground is now closed for the season and will be reopen next May.  Please call 518-834-9990 for reservations.

New: at the Campground & Recreation Center are new Mountain Bike Trails (w/rentals available) and a Disc Golf Course


Don't miss: The North Star Underground Railroad Museum and Heritage Center is also located near our Welcome Center (same parking) and provides an in-depth experience not to be missed.
