Suffern-Bear Mountain from Gate Hill Road is a high difficulty 15 mile out and back trail. At one point of the trail is a very difficult, but doable, rock scramble up the side of the mountain. At the top of the scramble is a primitive camping site with amazing views. The most difficult part about camping in this location is that you will have to carry your supplies up the mountain to the site. I would advise packing light if planning on camping here. The campsite is about 2.5 miles from the trailhead.
