Netflix 2025 thriller Sirens has quickly established itself as a must-watch series due to its captivating narrative and stunning visual storytelling. Central to the show’s ambiance is the fictional island of Port Haven, a secluded and mysterious community filled with secrets and suspense. Though fictional, the filming locations that bring Port Haven to life are very real—and they’re right in New York.
This detailed guide uncovers the filming locations used in Sirens and provides insights into visiting these picturesque and atmospheric sites in 2025. Whether you are a fan or a traveler in search of dramatic coastal beauty, here’s where Sirens was filmed and what makes these spots special.
The Setting: Port Haven and Its Real-World Counterparts
Port Haven is depicted as an isolated, affluent island with rugged cliffs, expansive mansions, and secluded beaches. To recreate this environment authentically, the production team chose Long Island’s North Shore in New York, specifically the towns of Lloyd Harbor, Northport, and Southold.
This region offers the natural diversity, historical architecture, and coastal charm needed to simulate the mystery and luxury of Port Haven, while remaining logistically feasible for filming.
Key Filming Locations in Long Island
Lloyd Harbor and Caumsett State Historic Park Preserve
Lloyd Harbor’s most notable contribution to the series is Caumsett State Historic Park Preserve, a vast parkland of 1,750 acres featuring dramatic cliffs, woodlands, and long stretches of beach along the Long Island Sound. The rugged cliffs and serene beaches of Caumsett provided the perfect atmospheric outdoor settings critical to Sirens’ dramatic tension.
This park was once the private estate of a wealthy industrialist before becoming a public state park and is now a favorite destination for hiking, bird watching, and photography.
Northport: The Kell Mansion and Harbor Village
The striking Kell mansion exterior was filmed at a private estate in Northport, an old harbor town with quaint shops and waterfront dining. Northport’s harbor and village scenes lend authenticity to the coastal lifestyle depicted in the series.
Though the mansion remains a private residence and is not accessible to the public, the surrounding town offers picturesque streets and waterfront views reminiscent of the show’s atmosphere.
Southold: Nautical Elegance and Social Scenes
Southold, a historic maritime town, contributed many of the yacht club and social event scenes in Sirens. This charming coastal town is known for its beautiful marinas, historic buildings, and community events.
Southold’s unique blend of maritime heritage and modern elegance helped enrich the series’ depiction of island life.
