Netflix’s Sirens (2025) stands out as one of the most visually captivating psychological thrillers to hit the screen in recent years. The series envelops viewers in a world of suspense, secrets, and stunning visuals, largely thanks to the distinctive filming locations that breathe life into the fictional island of Port Haven.
If you’re curious about where Sirens was filmed and want to discover the real places behind the story’s intense atmosphere, this detailed location guide uncovers the New York sites that served as the show’s breathtaking backdrop.
The Fictional Island of Port Haven and Its Real-Life Inspiration
Set on the mysterious island of Port Haven, Sirens features luxurious cliffside mansions, secretive families, and breathtaking seascapes. While Port Haven is a creation of fiction, the actual filming took place primarily on Long Island’s North Shore, New York – an area rich in natural beauty and historical charm that perfectly matched the tone of the series.
The main filming locations include Lloyd Harbor, Northport, and Southold — towns that collectively provided the varied and atmospheric environments needed for the show’s evocative storytelling.
Key Filming Locations
Lloyd Harbor and Caumsett State Historic Park Preserve
Lloyd Harbor served as a primary filming location, especially the Caumsett State Historic Park Preserve. This 1,750-acre state park features dramatic coastal cliffs overlooking Long Island Sound, dense woodland trails, and peaceful beaches. The park’s natural scenery offers a powerful visual element that enhances the show’s suspense and mysterious aura.
Known for its hiking paths, beaches, and rich wildlife, Caumsett State Park gives visitors the opportunity to see the very landscapes that set an eerie and beautiful stage for Sirens.
Northport: Mansion and Harbor Village
The grand Kell family mansion in Sirens is based on a real luxurious estate in Northport. Though the mansion itself is private, Northport’s harbor and village scenery were extensively used for filming.
Visitors to Northport can enjoy waterfront dining, boutique shopping, walking along historic harbors, and absorbing the charming small-town coastal vibe that enhances Sirens’ atmosphere.
Southold: Nautical Elegance and Social Scenes
Southold, a historic maritime town, was used for scenes depicting yacht clubs, social gatherings, and coastal community life. Its waterfront parks, marinas, and festivals contribute to the authenticity of the affluent island community portrayed in Sirens.
Behind the Scenes: Studio and Set Filming
Although the show extensively utilizes real locations, several interior scenes were filmed at Steiner Studios in Brooklyn. Here, the production team could meticulously design the interiors of the Kell mansion and other critical interior settings without the constraints of shooting on location.
