West Harbor
West Harbor is a sheltered anchorage on the Connecticut coast near Groton, where you drop the hook and take in the quiet of Long Island Sound. It's the kind of spot that feels tucked away, with the Thames River and Groton's submarine base — home to General Dynamics Electric Boat — just a short distance away if you're curious about the area's naval history.
