Sandwich s situated at the eastern entrance of the Cape Cod Canal, with about 8 miles of beautiful coastline on Cape Cod Bay. Like Bourne, Sandwich is cut into two pieces by the canal, with a small piece of land on the canal's north side. 

Sandwich is the oldest town on Cape Cod, and one of the most charming and quaint. Once famous for its glass-making, it is now a mostly residential town with beautiful white sandy beaches and plenty of open space. Sandwich has two harbors on Cape Cod Bay, and is the site of both Shawme-Crowell State Forest with its miles of hiking and horseback riding trails, and Scusset Beach State Reservation - a popular spot for swimming, fishing, and boat-watching. 

Villages in Sandwich include: East Sandwich, Forestdale, the historic Sandwich Village, and South Sandwich

Sandwich is bordered on the west by Bourne, on the south by Falmouth and Mashpee, and on the east by Barnstable.
