Explore the breathtaking filming locations of Netflix's 'Sirens' in Lloyd Harbor and Caumsett State Park, which masterfully crafted the show's captivating world of wealth and mystery. This thrilling series uses real New York settings to build its eerie, affluent atmosphere, drawing viewers into a visually stunning coastal intrigue.

When Netflix's dark comedy thriller 'Sirens' premiered in May 2025, it didn't just captivate audiences with its star-studded cast and twisty narrative; it also transported viewers into a visually stunning world of wealth, mystery, and coastal intrigue. The series, which follows the rough-around-the-edges Devon DeWitt (Meghann Fahy) as she searches for her sister Simone (Milly Alcock) within the opulent, secretive world of philanthropists Michaela and Peter Kell (Julianne Moore and Kevin Bacon), utilized its filming locations as a character in its own right. The show's eerie, affluent atmosphere wasn't just a product of clever set design—it was meticulously crafted from real places in New York that perfectly embodied the show's themes of allure and hidden danger.

The Quintessential Harbor Town: Lloyd Harbor

The fictional island village where the Kells reside and the local gossip swirls was brought to life in the very real Lloyd Harbor, New York. This location was a slam dunk for the production team. With a population hovering around just 4,000, Lloyd Harbor provided that perfect, insular small-town feel, juxtaposed with the unmistakable air of extreme affluence. The charming beach community, a stone's throw from New York City, is famously lined with multi-million dollar estates, having been home to celebrities like Billy Joel and Jerry Seinfeld. For 'Sirens', it was the ideal backdrop to portray a community that is both quaint and quietly observing the powerful, mysterious couple in their midst. All exterior scenes depicting the village's streets, shops, and harbor were filmed here, grounding the show's more surreal elements in a believable, tangible world.

The Heart of the Mystery: Caumsett State Historic Park Preserve

If Lloyd Harbor was the body of the Kells' world, then the Caumsett State Historic Park Preserve was its haunting soul. This historic estate, built in 1921 on the Gold Coast of Long Island, served as the primary filming location for the exterior of the Kells' dramatic cliffside mansion and its sprawling grounds. The show's narrative hinges on Michaela's passion for her aviary and wildlife reserve, and Caumsett's existing structures and rugged landscape were a perfect match.

The production made ingenious use of the location:

• The Historic Barn: The ornate Caumsett barn underwent a significant digital transformation. Using state-of-the-art CGI, it was morphed into the sleek, modern architectural marvel seen as the Kells' home. Talk about a glow-up!

• The Aviary: A temporary, functional aviary set was constructed on-site to house the raptors and birds central to Michaela's character.

• The Cliffs: Perhaps most importantly, the preserve's natural, jagged cliffs required no alteration. They provided the inherently eerie and perilous backdrop that symbolizes the show's central theme—the dangerous allure of the sirens' call.

This location, originally a country club and hunting preserve, added a layer of historical grandeur and slight decay that perfectly complemented the story's gothic undertones.

Building the Opulence Indoors: Steiner Studios

While the exteriors screamed natural beauty and historic wealth, the breathtaking interiors of the Kell mansion were a feat of cinematic construction. The majority of indoor scenes were filmed at Steiner Studios in the Brooklyn Navy Yard. This is where the magic of set design truly came into play. The production team built the lavish interiors from the ground up, including:

• The grand halls adorned with the Kells' collection of priceless art and sculptures.

• The luxurious guesthouse where Devon stays.

• The intricate interior of Peter Kell's lighthouse study, which relied on green screen technology to extend the view to the tumultuous seas outside.

Shooting at Steiner Studios allowed for complete creative control over the interior atmosphere, enabling the designers to craft spaces that felt both unimaginably rich and subtly claustrophobic—a gilded cage for its inhabitants.

Why These Locations Were a Perfect Match

The choice of locations for 'Sirens' was far from random. Each site served a specific narrative and thematic purpose:

Location	Role in 'Sirens'	Thematic Contribution
Lloyd Harbor	The island's village	Represents the observing public, gossip, and the contrast between normalcy and extreme wealth.
Caumsett Preserve	Exterior of the Kell estate & cliffs	Embodies natural beauty, old money, isolation, and underlying danger.
Steiner Studios	Interior sets of the mansion	Creates a controlled environment of opulent artifice and hidden secrets.

Together, these locations created a cohesive and immersive world. The blend of real, breath-taking exteriors with meticulously crafted interiors sold the fantasy. The show's directors, Nicole Kassell and Quyen Tran, utilized these settings to enhance the dark comedy and drama, making the environment a silent but powerful player in the story. The foggy chaos, the eerie calm of the preserve, and the glossy sheen of the interiors all work in tandem to keep the audience guessing—just as Devon is—about what is real and what is a carefully constructed illusion.

In the end, 'Sirens' proves that location scouting is an art form. By choosing spots like Lloyd Harbor and Caumsett, the show taps into a very specific je ne sais quoi—a blend of Northeastern elite enclave and mythic, almost primal, landscape. It’s a testament to the production that viewers in 2026 are still dissecting not just the plot twists, but the very world in which they unfolded. The locations didn't just host the filming; they helped tell the tale of allure, deception, and the secrets that lie behind the most beautiful facades.
