Marcellus Falls is a 0.1 mile lightly trafficked out and back trail located near Marcellus, New York that features a waterfall and is good for all skill levels. The trail is primarily used for walking and nature trips and is accessible year-round.
This is on private property so all you can do is look at it from the road. However, you can explore all around the river downstream from it.
I haven't verified these directions, but this is what I found online: http://www.footprintpress.com/Waterfalls/marcellusfalls.htm
This was the first trial my son and I did. The water fall is on private property so the only thing you could do is take pictures from the road like I did. Very disappointing but the trip was somewhat save due to the parking area where the small creek (about 50 feet long) provided a nice area to eat and just get your feet wet.
