Mossy Cascade Brook Falls - also called Mossy Cascade - is a 40-foot-high drop in Mossy Cascade Brook, a tributary to East Branch of the Ausable River.
To see the falls, drive 2 miles south on NY 73 from Keene Valley. After the road crosses the Ausable River, you'll see a parking area on the left side.
Once you park, follow the marked trail toward "Hopkins - Mossy Cascade." Although the trail is only 0.7 miles, flooding almost two decades ago has made the trek moderately difficult.
