The Adirondack Park Loop is almost entirely within the boundaries of the Adirondack Park. Starting just outside of Schenectady, New York in Niskayuna, the route travels north through Saratoga Springs before crossing the “Blue Line”, the term that many locals and frequent visitors use for crossing the boundary into the park. Adirondack Park is the largest publicly protected area in the lower forty-eight states, greater in size than Yellowstone, Everglades, Glacier and Grand Canyon National parks combined.
