Tupper Lake is known as the Crossroads of the Adirondacks because of its location in the center of the Adirondack Park. The lake is 9 miles long beginning about 12 miles north of the town of Long Lake, NY and extending parallel along Route 30 into the town of Tupper Lake, NY. New York Route 30 extends along the lake’s east side. The west side of the lake is mostly wilderness, inaccessible by road but lovely to visit by boat.
