Welcome to Four Mile River Marina!

Four Mile River Marina is a private tidal marina located in South Lyme Connecticut on Four Mile River. The river forms a border between South Lyme and East Lyme and flows into Long Island Sound between Rocky Neck State Park and Point of Woods.

Due to the nature of the river, we can accomodate only boats up to 25’long. Our boaters are mostly families and fisherman from the Connecticut and Western Massachusetts area who enjoy our natural and peaceful surroundings.

 2019 season: 4/2019 to 10/2019
