A Premier Destination for Families and Fun

Three Belles Marina is located on pristine Smith Cove just minutes from the quaint village of Niantic Connecticut and just a few miles from Interstate 95. We are an independently owned and operated full-service marina that caters to your every boating need, from service to hull repair and even a picnic lunch – we are committed to making your boating experience enjoyable. Our protected cove is minutes from the Long Island Sound and some of the best boating and fishing grounds on the eastern seaboard.

You can enjoy a quick trip to Montauk, Fishers Island or a weekend retreat to Block Island. Our unique location puts us halfway between the beautiful Connecticut River to our west and the Thames River to the east, all within a day’s journey. After a day on the sea, consider a stroll into Niantic for dinner, a movie and some shopping. If you are feeling lucky, you can take a quick 15-minute ride to Mohegan Sun or Foxwoods Casinos and enjoy an evening of chance and entertainment.
