and Essex County. Most of this area is part of the Adirondack Park, offering tremendous views of the Adirondack High Peaks region and many recreational opportunities in the park and along the relatively undeveloped coast line of Lake Champlain. The city of Plattsburgh is to the north, and the historic town of Ticonderoga is in the southern part of the region. The northern part of Lake George is located at, and near Ticonderoga, and therefore is a part of the Champlain Valley.
