 Port Kent, NY is splendidly located on the shores of Lake Champlain; about a quarter of a mile from the D & H Station or 3 miles over new cement road from Ausable Chasm, which is on the main highway between New York and Montreal. It's the main ferry crossing between the Adirondacks and Green Mountains. The Lakeside Inn and cottages accommodates 125 guests. Rooms with or without running water and en suite with private bath.
