Steeped in maritime heritage, Duxbury Harbor once thrived as a shipbuilding and shipping center in the 17th and 18th centuries. Today, it remains a hub for recreational boating, offering ample opportunities for fishing, kayaking, paddleboarding, and simply enjoying the tranquil waters. Its protected location, guarded by Duxbury Beach to the east and Saquish Neck to the south, creates a calm haven for outdoor activities.

Duxbury Harbor has three marinas on the waterfront.
