Netflix’s Sirens (2025) has captivated audiences with its thrilling narrative and visually stunning coastal scenes. Central to the series is the fictional island of Port Haven—a place full of mystery, wealth, and suspense. Though Port Haven exists only in the realm of fiction, the stunning filming locations that brought it to life are very much real and accessible. For fans and travelers keen to explore where Sirens was filmed, this comprehensive guide sheds light on the key New York locations that shaped the series’ iconic aesthetic.
The Fictional Port Haven and Its Real-Life Inspirations
Port Haven’s character as a remote, affluent island with towering cliffs, sprawling estates, and serene beaches was crafted with real-world places in mind. The filmmakers turned to Long Island’s North Shore, known for its historic mansions, coastal beauty, and quaint villages, to emulate this captivating setting.
The primary shooting locations consist of Lloyd Harbor, Northport, and Southold—each imbued with natural charm and architectural splendor that elevate the narrative and atmosphere of Sirens.
Detailed Filming Locations
Lloyd Harbor and Caumsett State Historic Park Preserve
Lloyd Harbor’s natural beauty provided many of the outdoor sequences for Sirens, primarily within Caumsett State Historic Park Preserve. Encompassing 1,750 acres, Caumsett features dramatic coastal cliffs, vast forests, winding trails, and peaceful beaches. These diverse environments added depth to the show’s outdoor scenes—from tense encounters by the sea to solitary walks through dense woodland.
Historically a private estate owned by Marshall Field III, Caumsett transformed into a public park in the 1960s and today serves as a destination for hiking, birdwatching, photography, and conservation.
Northport Village and the Kell Mansion
The prominent Kell family mansion showcased in Sirens is based on a private home in Northport, a picturesque village along Long Island’s coast. The mansion’s imposing Georgian architecture and vast grounds capture the show’s themes of class, power, and secrecy.
While the mansion itself is not open to visitors, Northport’s harbor, cafes, boutiques, and waterfront walks provide fans an immersive experience into the community life portrayed in the series.
Southold’s Historic Maritime Charm
Southold, a coastal town with deep maritime roots, framed much of the social and yacht club scenes in Sirens. Its harbors, historic buildings,
and vibrant community life lend visual authenticity and a sense of real-world elegance.
Visitors to Southold can explore museums, attend local festivals, indulge in winery tours,
and enjoy fresh seafood at waterfront restaurants, reflecting the rich lifestyle echoed in Port Haven.
