Whiteface Mountain is the fifth-highest mountain in the U.S. state of New York, and one of the High Peaks of the Adirondack Mountains, located in the town of Wilmington in Essex County. Set apart from most of the other High Peaks, the summit offers a 360-degree view of the Adirondacks and clear-day glimpses of Vermont and Canada, where Montreal can be seen on a very clear day.
