East Harbor
East Harbor is a natural anchorage off Groton, Connecticut, where you drop the hook and take in the sweeping coastal scenery of the Thames River estuary. It's a quieter alternative to the busier New London side, with the iconic New London Ledge Lighthouse visible nearby — a striking French Second Empire structure worth the look. The surrounding waters sit at the crossroads of Long Island Sound, giving you classic New England tidal atmosphere without much fuss.
