Netflix’s Sirens Filming Locations (2025) has enthralled viewers with its gripping storyline and stunning visual backdrop. Central to the show’s haunting atmosphere is Lloyd Harbor, New York—the primary filming location for the fictional island of Port Haven. This guide explores Lloyd Harbor’s unique qualities that made it the perfect setting for Sirens, its rich history, spectacular natural features,
and why it remains special beyond the screen.
Where Is Lloyd Harbor?
Lloyd Harbor is a picturesque village located on the North Shore of Long Island in Suffolk County, New York. Covering about 9.2 square miles with a population of around 3,400 residents, it is one of Long Island’s most exclusive and scenic communities. The harbor itself is a sheltered inlet along the Long Island Sound, offering stunning waterfront views, pristine beaches, and expansive natural preserves.
Named after James Lloyd, a prominent 17th-century landowner, Lloyd Harbor has preserved much of its historic charm and natural beauty, balancing an affluent residential community with protected public lands.
Why Was Lloyd Harbor Chosen for Filming Sirens?
Perfect Blend of Seclusion and Beauty
Sirens required a location that embodied isolation, wealth, and natural beauty. Lloyd Harbor’s sprawling estates and expansive natural landscapes provided an authentic backdrop that cinematic producers desired to create the fictional Port Haven. The village’s quiet elegance and secluded beaches complemented the tone of mystery and suspense.
Expansive Natural Reserves
One of Lloyd Harbor’s crown jewels is the Caumsett State Historic Park Preserve, encompassing over 1,700 acres of wooded trails, cliffs, and shoreline. This natural preserve provided the dramatic and atmospheric cliffside scenes prominent in Sirens. Its rugged open spaces contrast perfectly with the polished mansions seen in other parts of the area.
Convenient Access and Privacy
Logistically, Lloyd Harbor was more accessible and film-friendly than actual remote New England islands, which also influenced its selection. The area’s low population density allowed filming with fewer interruptions while providing the needed privacy for a production involving seasonal shoots and large crews.
