The Army Corps of Engineers maintains the Cape Cod Canal Visitor Center which introduces visitors to the history, features, and operation of the canal. Features include a retired US Army Corps of Engineers patrol boat, a 46-seat theater showing continuous DVD presentations on canal history, canal flora and fauna, real time radar and camera images of the waterway, and a variety of interactive exhibits. Corps Park Rangers staff the center and provide free public programs on a variety of subjects. The Visitor Center is open seasonally from May to October, and admission is free. It is located on Moffitt Drive in Sandwich near the canal's east end. A second seasonally staffed center is at the Herring Run along Scenic Highway.
