Netflix’s 2025 psychological thriller Sirens has taken audiences by storm, not only for its gripping plot and stellar performances but also for its breathtaking and carefully chosen Netflix’s Sirens Filming Locations. Central to the show’s visual identity is Lloyd Harbor, New York—a seemingly quiet and exclusive village that doubles as the fictional island of Port Haven, home to the enigmatic Kell family estate.
If wondering where Sirens was filmed and why Lloyd Harbor was chosen, this detailed guide covers everything about this remarkable location, its historical and natural significance, and what makes it an irreplaceable backdrop for the series.
Where Is Lloyd Harbor?
Lloyd Harbor is an affluent village situated on the North Shore of Long Island in Suffolk County, New York. Covering approximately 9.2 square miles, it is known for its expansive greenery, waterfront views, and low population density—about 3,400 residents—offering privacy and exclusivity desired by many wealthy homeowners.
Named after James Lloyd, an early settler who acquired the land in 1676, the area boasts pristine beaches, forested parks, and some of the most desirable real estate on the East Coast. The harbor itself provides a scenic and serene natural harbor, perfect for boating and waterfront activities.
Why Was Lloyd Harbor Chosen for Sirens?
Exclusive and Picturesque Setting
The show’s creators needed a location that embodied wealth, luxury, and mystery. Lloyd Harbor’s quiet opulence and secluded environment made it an ideal choice. The village’s manicured landscapes, sweeping waterfront properties, and tastefully preserved natural areas offered a rich visual palette directly matching the fictional Port Haven’s aesthetics.
Natural Beauty with Privacy
Unlike more bustling tourist locales, Lloyd Harbor provides an unparalleled privacy felt by the characters on Sirens. Its vast parks and beach preserves such as the adjacent Caumsett State Historic Park Preserve provide dramatic cliffs, sandy beaches, and wooded trails used extensively in the series to convey isolation and suspense.
Practical Filming Logistics
Production designer John Paino highlighted that unlike an actual New England island like Nantucket, where homes are often in use during summer, Lloyd Harbor provided a more feasible filming environment in summer 2024 and 2025. The proximity to New York City
and established film infrastructure in the region also made it a convenient and cost-effective base for shooting.
Key Filming Spots in Lloyd Harbor and Surroundings
Caumsett State Historic Park Preserve
Perhaps the most iconic outdoor location linked to Sirens, Caumsett Park offered more than 1,700 acres of natural terrain to film cliffside sequences, beach scenes, and the surrounding woodland that perfectly underscore the show’s moody atmosphere.
The park was originally a private estate for investment banker Marshall Field III before becoming a public historic park in 1961. Today, it’s popular for hiking, bird watching, and photography, giving fans a chance to walk the same trails seen on screen.
The Cliff House: The Kell Mansion
While most of the estate scenes were filmed at a private home in neighboring Northport, Lloyd Harbor’s Caumsett Park cliffs
and reserves were essential for portraying the mansion’s dramatic surroundings. Extended through clever set design and CGI, the mansion’s imposing presence reflects themes of secrecy, wealth, and isolation—central to the narrative.
What Makes Lloyd Harbor Special Beyond Sirens?
A Rich Historical Heritage
Lloyd Harbor’s roots trace back to the Matinecock Native Americans, who first inhabited the area before European settlement. The community’s historical landmarks and preserved estates showcase an ongoing commitment to protecting its heritage and environment.
Celebrity Appeal and Real Estate Rarity
The village is well-known for its celebrity residents and exclusivity, attracting high-profile homeowners including musicians, actors, and business leaders. The scarcity of homes for sale means properties in Lloyd Harbor are often coveted
and represent the pinnacle of luxury living on Long Island.
Natural and Recreational Resources
With miles of shoreline, state parks, equestrian centers, and golf courses, Lloyd Harbor offers a range of recreational activities in a peaceful setting. Caumsett State Park alone is a treasure trove of natural beauty, making the area a beloved escape for residents and visitors alike.
