We love Cape Cod and so will you! Located on the lower-Cape, Harwich is a popular vacation spot with three active harbors, Saquatucket, Wychmere and Allen Harbors, all in Harwichport. The town is known for its many cranberry salt bogs, which produce cranberries that are commercially farmed. Long Pond is the largest lake on Cape Cod and serves as a private airport for planes which can land on water.
