Netflix’s 2025 psychological thriller Sirens has quickly become a standout series due to its gripping story, impeccable performances, and most notably, its captivating locations. The fictional island of Port Haven, which serves as the heart of the series’ suspenseful narrative, was brought to vivid life through real places in New York. For fans and travelers intrigued by the show’s setting, here’s the definitive guide to the filming locations used for Sirens and tips on how to explore these scenic and atmospheric places.
Understanding the Fictional Port Haven and Its Real-Life Counterpart
Port Haven is portrayed as a remote, affluent island with stunning cliffs, sprawling mansions, and an air of mystery. Though a fictional creation, the locations filmed to represent Port Haven are situated on Long Island’s North Shore, New York, renowned for its picturesque coastline, historic estates, and charming small towns.
The primary filming hubs for Sirens included Lloyd Harbor, Northport, and Southold—each offering a unique slice of coastal elegance and natural beauty that helped shape the series’ intense and immersive atmosphere.
Filming Locations in Detail
Lloyd Harbor: The Natural and Dramatic Backdrop
Lloyd Harbor serves as the primary natural setting for many Sirens outdoor scenes. Central to this area is the Caumsett State Historic Park Preserve, a stunning 1,750-acre park featuring cliffs overlooking the Long Island Sound, hiking trails, beaches, and dense woodlands.
The park’s dramatic cliffs and secluded beaches afford breathtaking vistas that enhanced the show’s suspenseful and mysterious mood. Its historic past, once as a private estate before becoming a public park, lends historical depth to its natural grandeur.
Visitors today can walk the same trails and photograph the same vistas captured on screen, making Caumsett a pilgrimage site for fans of the series and nature lovers alike.
Northport: The Iconic Kell Family Mansion and Harbor Village
The Kell mansion, the series’ emblematic family estate, was filmed at a private estate in Northport. While the mansion itself is a private residence, Northport’s harbor and village scenes offer public spaces resonating with the coastal charm portrayed in Sirens.
Northport boasts a lively waterfront with shops, cafes, galleries, and restaurants, allowing visitors to experience the town’s maritime traditions and vibrant community—much like the fictional Port Haven’s social setting.
Southold: A Nautical and Cultural Gem
Southold provided the setting for several social and yacht club scenes in the show. Known for its maritime history, seafood restaurants, wineries, and cultural events, Southold contributed both aesthetic richness and authenticity to the show’s narrative fabric.
Visitors to Southold can enjoy waterfront strolls, winery tours, festivals, and museums that celebrate the area’s rich coastal heritage.
