New London County, Connecticut

New London County occupies southeastern Connecticut, where the Thames River meets Long Island Sound. It’s submarine country, with the Naval Submarine Base keeping things shipshape. Mystic Seaport draws tourists, while Mohegan Sun lights up the night.

You’ll find quiet farm towns not far from bustling marinas. New London County has a strong nautical vibe with a side of rural charm. It’s a place where you can enjoy both salty sea air and hay fever on the same day.

The county is a bit of a chameleon. It’s part maritime New England, part casino glitz, and part quiet countryside. It offers the best of several worlds, and it sounds like a lot of fun to me.
