About 2 miles north of Glen Island on the east side, you'll find a great picnic spot at the day use area known as Black Mountain Point.
Black Mountain Point is north of the Black Mountain Shore campsites and features multiple docking sites along the shoreline that lead to picnic areas. It's part of the Glen Island Group, and you must have a day use pass to use the picnic sites.
Please Note: Dogs and other pets are prohibited on the DEC's day use facilities, which includes Black Mountain Point.
