 Much of NY 9N runs alongside either a river or a lake. It follows the Hudson River through northern Saratoga County and southern Warren County, the entirety of Lake George's western shoreline, the west edge of Lake Champlain between Ticonderoga and Westport, and the Ausable River from Keene to Keeseville. The other portions of NY 9N pass through predominantly rural and mountainous regions of the Adirondack Mountains.
