Medium-sized marina with multiple piers, several buildings including possible service structures, and a medium surface parking lot amid surrounding residential areas.
Three Belles Marina is situated in East Lyme, Connecticut, along the Niantic River where it meets the Long Island Sound, a sheltered estuary on the Atlantic Coast that provides calm waters for boating enthusiasts. This marina serves recreational sailors and boaters exploring the coastal waters of the Long Island Sound region, which offers access to both protected bays and nearby Atlantic Ocean routes. Its location in southeastern Connecticut makes it ideal for day trips and seasonal sailing in this historic New England coastal area.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
