Glen Ellis Falls is accessed via a very well marked parking area on Route 16 in Pinkham Notch. There is a tunnel from the parking area under Route 16. Follow the trail. In order to access the base of the falls, you'll climb down a long series of stone stairs.
There are 2 jump points right on top of eachother. About a 6-7 foot difference. The lower one is on the other side of the lookout platform (a 3'x3' rock slab) and the higher is off the rock wall/ railing of the lookout point.
