The Cold River begins at the height of land in Evans Notch, a pass through the eastern White Mountains. Maine Highway 113, a narrow two-lane road, passes through the notch, following the Cold River on the south side and Evans Brook, a tributary of the Androscoggin River, on the north. The Cold River, flowing south, picks up the Mad River, a short stream with waterfalls that flows off the southern faces of East Royce and West Royce mountains, then reaches the southern base of Evans Notch at the junction of Basin Brook, coming out of a large glacial cirque to the west, where the Cold River national forest campground is located.
