Netflix’s Sirens is one of 2025’s most talked-about psychological thrillers, captivating audiences with its gripping story and breathtaking settings. But many fans and viewers have been asking: where was Sirens film?
Despite its fictional New England island setting call Port Haven, the entire miniseries was shot in some of the most beautiful locations in New York State. This behind-the-scenes look guides you through the real-life spots that brought Sirens to life, making it not only a dramatic story but also a visual feast that showcases coastal elegance
and historic estates.
The Fictional World of Port Haven and Its Real-Life Counterpart
The show’s fictional setting, Port Haven, evokes the feel of iconic New England locations such as Nantucket or Martha’s Vineyard with its pristine beaches, cliffs, and grand mansions. Remarkably, Sirens did not film in the New England states. Instead, production chose Long Island, New York, for the stunning waterfront
and historic estates that embody that upscale island atmosphere while remaining logistically feasible for filming.
The production crew utilize towns including Lloyd Harbor, Northport,
and Southold on Long Island’s northern coast. These areas, with their exclusive homes
and serene natural beauty, provide the perfect canvas to portray the mysterious and opulent world of the Kell family.
Lloyd Harbor: The Heart of Sirens’ Filming
Most prominently, Sirens was film in Lloyd Harbor, one of Long Island’s most exclusive waterfront communities. The area is known for its rich history, sprawling estates, and celebrity residents. The centerpiece of the series—the Kell family’s cliffside mansion, famously known as “The Cliff House”—is primarily film in this area.
The dramatic cliffs and beach scenes were shot at Caumsett State Historic Park Preserve, locat on the Lloyd Neck peninsula. This 1,750-acre park, once a private estate
and hunting preserve purchase by investment banker Marshall Field III in 1921, is now a state historic park offering hiking, bird-watching,
and nature photography. The rugg cliffs and natural woodlands of Caumsett provide an eerie yet stunning backdrop consistent with the series’ ominous tone.
Northport: The Iconic Kell Estate Exterior
For the exterior shots of the Kell mansion, a grand private home in Northport was select. While the house wasn’t originally as large as need for the show’s vision, the production team expand it through elaborate set extensions that include adding pergolas, a turret,
and other elements to convey the “oligarch-like” luxury the creators want to emphasize.
According to the production designer John Paino, who also worked on other acclaim shows like Big Little Lies, the goal was to create a home that felt perfect but also unsettling, with meticulously manicure gardens
and over-the-top interiors symbolizing control and perfectionism. The Northport location gave Sirens its rich and eerie mansion feel.
Other Filming Locations Around Long Island
Besides Lloyd Harbor and Northport, filming also took place in Southold, another charming town along the coast of Long Island. Some beachside mansion scenes and yacht club backdrops were shot here, contributing to the show’s nautical
and coastal vibe.
In addition to outdoor locations, many interior scenes were film on soundstages at Steiner Studios in Brooklyn, where elaborate sets allow for full creative control over pivotal scenes inside the Kell estate
and other settings. The blending of real Long Island landscapes with detailed studio sets help create the surreal, tense atmosphere that defines Sirens.
Why Long Island for Sirens?
The choice to film in Long Island instead of authentic New England locations was motivate by practicality and the unique character of the area. While Sirens evokes recognizable New England aesthetics, Long Island provide the advantage of accessible filming permissions during the summer season, along with diverse landscapes—from coastal cliffs to historic manors.
Moreover, the variety of locations within a relatively small radius allow the production to efficiently film the necessary wide range of scenes without relocating extensively, an important factor in modern TV and film production.

While the Kell estate is a private home in Northport, visitors can enjoy the surrounding towns and nearby waterfront views that capture the essence of Sirens’ luxurious coastal setting.
The Appeal of Location in Storytelling
The exquisite and sometimes eerie settings of Sirens do more than provide a pretty backdrop—they amplify the show’s themes of wealth, power, secrecy, and suspense. The isolation of the cliffside mansion, the vastness of the estate’s grounds, and the natural harshness of the cliffs symbolize the characters’ tangled relationships and hidden motives, making the filming locations integral to the storytelling.
