Medium-sized marina with multiple piers packed with boats, a central building, and a surface parking lot with several vehicles amid surrounding wooded areas.
Three Mile Harbor Marina is located in Springs, a hamlet within the town of East Hampton on Long Island's East End, New York, where it sits along the shores of Three Mile Harbor, a protected inlet that opens to the Atlantic Ocean's coastal waters. This marina serves recreational boating and sailing enthusiasts who navigate the harbor's calm waters and venture out into the nearby Atlantic, taking advantage of the region's scenic bays, inlets, and ocean access. Springs, part of the affluent Hamptons area, positions the marina as a gateway to the broader maritime activities of Long Island's South Fork.
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.
