Whether viewers want to trace the steps of the cast or plan a trip to the scenic locations, understanding the actual filming sites adds a new layer of appreciation for the series.
This guide takes you through the authentic filming locations of Sirens, primarily focusing on the lush and mysterious spots along Long Island’s coastline and historic estates that brought the series’ captivating scenery to life. If you’re a traveler, a thriller enthusiast, or a die-hard fan, this detailed exploration provides everything you need to know about the real-world locations behind the series.
The Show’s Setting vs. Real Locations: An Overview
Sirens portrays a fictional secluded island named Port Haven, evoking the charm of classic New England coastlines with cliffs, sprawling estates, and hidden secrets. Interestingly, the production did not film in New England. Instead, the crew selected Long Island, New York, as the ideal filming environment—thanks to its scenic landscapes, accessibility, and variety of preserved historic locations.
The series’ exclusive mansion, cliffside vistas, and coastal scenery were brought to life through careful location selection, mainly in Lloyd Harbor, Northport, and Southold. These towns offer a perfect blend of natural beauty
and historic charm, making them ideal setting stand-ins for the fictional world of Sirens.
Why Long Island? The Best Choice for Sirens Filming
Long Island provided an optimum backdrop for Sirens’ atmospheric scenes, especially because of its coastline, historic mansions, and exclusive neighborhoods. Here are some compelling reasons why the production chose this region:
-
Diverse Landscapes: From rugged cliffs and pristine beaches to lush estates, Long Island’s varied scenery allowed the filmmakers to craft multiple settings within a small geographical area.
-
Accessibility: Compared to remote New England locales, Long Island offers better logistical convenience, making it easier to coordinate filming schedules and logistics.
-
Historic and Luxurious Architecture: The region boasts many estates and mansions that deliver the opulent yet mysterious aesthetic necessary for the series.
Key Filming Locations of Sirens in Long Island
Lloyd Harbor and Caumsett State Historic Park
The heart of Sirens’ filming takes place in Lloyd Harbor, known for its affluent waterfront properties and scenic views. The iconic Kell estate, a central location in the series, was shot at a private mansion nestled within Caumsett State Historic Park Preserve. This 1,750-acre park, formerly a private estate, features cliffs along the Long Island Sound and scenic walking trails.
Caumsett not only provided the perfect natural backdrop with its rugged cliffs
and wild coastal terrain but also enhanced the mystery surrounding the series’ plot. Many outdoor scenes, especially cliffside shots
and beach scenes, were shot in the park, leveraging its natural beauty.
Northport: The Majestic Kell Mansion
The mansion that serves as the primary residence of the Kell family was filmed at a luxurious private estate in Northport. The house’s exterior was designed to look like an opulent, isolated coastal mansion. The production team extended its features using CGI and set decoration to evoke an aura of wealth, secrets, and mystique.
The Northport estate, with its grand architecture and proximity to the water, contributed significantly to the series’ eerie
and suspenseful tone, making it one of the most recognizable filming spots.
Southold: Seaside and Nautical Settings
Additional scenes, particularly those involving the yacht club and seaside character interactions, were filmed in Southold. Its scenic harbors, historic marinas, and coastal estates enhance the authentic nautical vibe required for the series.
Behind-the-Scenes Insights from Production
The decision to film in Long Island’s coastal towns was driven by production needs and aesthetic considerations. The production team, led by seasoned directors and location scouts, prioritized areas that could deliver atmospheric moods—both serene and foreboding.
According to industry insiders, the use of real locations like Caumsett State Park
and private estates helped Sony’s Sirens achieve a cinematic quality while maintaining cost efficiency. The blending of natural landscapes with studio-driven set extensions created a seamless and immersive experience for viewers.
Visiting the Filming Locations: A Must-Do for Fans
For fans eager to see where the magic was made, California’s Caumsett State Historic Park offers walking trails and scenic viewpoints that mirror many scenes from Sirens. The park is accessible to the public, with amenities that support leisurely visits.
While the actual Kell mansion estate remains private, nearby towns like Northport
and Southold are open for exploration. Visitors can enjoy luxurious waterfront dining, historic sites,
and charming shops that evoke the atmosphere of the series.
Pro Tip: For the most authentic experience, plan a visit during the late afternoon to enjoy sunset views over the water, which fans will recognize from key scenes.
The Impact of Location on the Series’ Atmosphere
The choice of filming locations directly influences the mood of Sirens. The rugged cliffs and secluded estates symbolize the series’ themes of isolation, secrets, and hidden truths, making the natural scenery as much a character in the story as the actors.
Having real locations with historic and natural charm adds an authentic touch, making the series relatable and visually compelling. The geographic authenticity also enhances the storytelling, immersing viewers in the mysterious world of Port Haven.
