The Grand Canyon of the Adirondacks in northern New York.
Established in 1870, Ausable Chasm is the oldest natural attraction in the United States. It is a paid attraction and there are many things to do, so you can plan on spending a couple of hours up to a full day here. For the non-adventure seekers, you can take one of many trails along the chasm rim to take in the views. The more intrepid can get their thrills on the Family Adventure Trail across and along the chasm. You can even cool off with a rafting or tubing ride through the narrowest part of the chasm.
