Two of the most sought-after hamlets on Long Island's South Fork, explained — where they sit, how to reach them, and why both are unmistakably part of the Hamptons.
Sagaponack and Water Mill are neighboring hamlets in the Town of Southampton, on the South Fork of eastern Long Island, New York — and yes, both are firmly in the Hamptons. If you are trying to place them on a map before a visit, a purchase, or a move, here is exactly where they are and how everything fits together.
Buyers, renters, and first-time visitors ask the same two questions constantly: where is Sagaponack, New York, and where is Water Mill, New York? The confusion is understandable. The Hamptons is not a single town but a string of villages and hamlets spread across two townships on Long Island's East End, and the small, quiet places — the ones with the highest price tags and the least signage — are often the hardest to locate. This guide answers both questions precisely, then adds the context that actually matters when you are deciding where to spend your time or your money.
Sagaponack is an incorporated village and hamlet in the Town of Southampton, Suffolk County, on the South Fork of Long Island, New York. It sits directly on the Atlantic Ocean, roughly 95 miles east of Midtown Manhattan and about a two-hour drive from New York City in ordinary traffic. Its ZIP code is 11962 and it shares the 631 area code with the rest of the East End.
If you picture the South Fork as a long, narrow arm of land reaching east into the Atlantic, Sagaponack occupies a prime stretch of its southern, oceanfront edge. It is bordered by Bridgehampton to the west, by Wainscott and the Town of East Hampton to the east, and by Sag Harbor and Noyac to the north. The village runs from the ocean beaches inland across some of the most valuable farmland in the country, with Sagaponack Pond and Sagg Pond breaking up the shoreline.
So when someone asks where is Sagaponack, NY, the shortest accurate answer is this: it is an oceanfront village on the South Fork, inside the Town of Southampton, between Bridgehampton and East Hampton. The name itself is old — it derives from a Shinnecock Nation word meaning "land of the big ground nuts," and the community was first settled by Europeans around 1653 under the name "Sagg." For most of its history it was an unincorporated hamlet; residents voted to incorporate as a village in 2005 to gain more control over zoning and preserve the open, agricultural character that makes it so distinctive.
Despite carrying the reputation of a billionaires' enclave, Sagaponack is genuinely small. The 2020 census counted a permanent population of roughly 770 people across about 4.7 square miles. It remains the kind of place where a one-room schoolhouse still operates — the Sagaponack School serves the youngest grades and is one of the last active one-room schools in New York State, with older students attending nearby Bridgehampton, Sag Harbor, or East Hampton districts.
Yes — Sagaponack is unambiguously in the Hamptons. It is one of the Hamptons villages, located within the Town of Southampton on the South Fork, and it is frequently described as the single most expensive neighborhood in the entire region. In multiple national surveys its 11962 ZIP code has ranked among the priciest in the United States, with median home sale prices climbing into the multi-millions and many oceanfront estates trading well above that.
The reason people occasionally hesitate is that "the Hamptons" is an informal, cultural label rather than an official government designation. There is no incorporated municipality literally called "The Hamptons." Instead, the name covers a collection of communities across the Towns of Southampton and East Hampton — including Southampton, Water Mill, Bridgehampton, Sagaponack, Wainscott, East Hampton, Amagansett, Sag Harbor, Montauk, and the western villages. Because Sagaponack sits squarely inside that footprint, on the ocean, between two of the best-known Hamptons names, it is about as "Hamptons" as a place can be. If anything, it is one of the addresses that defines the region's reputation for privacy and price.
Most people reach Sagaponack by car, taking the Long Island Expressway east to Route 27 (Sunrise Highway), which becomes Montauk Highway as it threads through the South Fork. Sagaponack Road and Sagg Main Street lead south from Montauk Highway down toward the village center and the ocean beaches. The hamlet does not have its own train station; the closest Long Island Rail Road stops are in Bridgehampton and Southampton, and the Hampton Jitney and Hampton Luxury Liner coaches make regular runs from Manhattan to the surrounding villages. For those traveling by air, East Hampton Airport is a short drive east, and the major New York airports are roughly two hours west.
Once you are there, the geography is easy to read. Sagg Main Street runs down to Sagg Main Beach, one of the area's beloved ocean beaches; the surrounding lanes wind past preserved farm fields, hedgerows, and gated estates. Everything is close — the shops and restaurants of Bridgehampton are minutes to the west, and Sag Harbor's historic waterfront village is a short drive north.
Water Mill is a hamlet and census-designated place in the Town of Southampton, Suffolk County, on the South Fork of Long Island, New York. It lies between Southampton Village to the west and Bridgehampton to the east, roughly three miles east of Southampton Village and about 90 miles east of Manhattan. Its ZIP code is 11976, and like the rest of the East End it uses the 631 area code.
Whereas Sagaponack hugs the ocean, Water Mill stretches from the Atlantic shoreline northward across farmland and up to the bays of Peconic — including frontage on Mecox Bay and the smaller inlets that make the hamlet especially appealing to buyers who want water views without paying strictly oceanfront prices. The 2020 census recorded a population of about 2,506 residents across nearly 13 square miles of land and water. Its approximate coordinates are 40.92° N, 72.35° W, and it sits at a modest elevation of about 39 feet above sea level.
The hamlet takes its name quite literally. A settler named Edward Howell built a water-powered grist mill here in 1644 to grind grain for the early Southampton colony, and that history is still visible today. Water Mill is the only settlement on the South Fork with both a functioning watermill and a windmill, both listed on the National Register of Historic Places, and the old mill now operates as the Water Mill Museum. In recent decades the hamlet has become an upscale resort community and cultural destination — the Parrish Art Museum relocated to Water Mill in 2012, and the experimental Watermill Center sits nearby.
You will often see the name written as a single word — "Watermill" — in searches, listings, and casual conversation. The official spelling is two words, Water Mill, but Watermill, NY and Water Mill, NY refer to exactly the same place: the hamlet on Long Island's South Fork in the Town of Southampton. Whichever spelling you use, the location is identical. It runs along Montauk Highway between Southampton and Bridgehampton, with the ZIP code 11976.
Directions are much like reaching Sagaponack. Drive east on the Long Island Expressway to Sunrise Highway and continue onto Montauk Highway, which passes straight through the heart of Water Mill — you will know you have arrived when you see the windmill on the village green. The Southampton and Bridgehampton LIRR stations flank the hamlet, and the Hampton Jitney stops nearby. Because Water Mill sits at the western gateway to the "estate section" Hamptons, it is often the first true Hamptons hamlet drivers reach after leaving the more built-up western towns behind.
Yes. Water Mill is one of the classic Hamptons hamlets, positioned right between Southampton Village and Bridgehampton — two of the best-known names on the East End. It offers the full Hamptons profile in miniature: ocean beaches to the south, working farm stands and vineyards inland, waterfront estates on Mecox and Burnett Creek, and a quiet, low-key village center anchored by that historic windmill. For many buyers it represents a sweet spot in the Hamptons — central, scenic, and slightly more private than the busier village downtowns on either side.
Both hamlets belong to the same township and share the same fundamental Hamptons DNA, but each has its own character. The table below lays out the essentials side by side.

Understanding exactly where Sagaponack and Water Mill sit is the first step toward understanding their real estate. Location is everything on the South Fork, and a few hundred yards — south of the highway versus north of it, oceanfront versus pond-view versus bayfront — can mean a difference of many millions of dollars. Sagaponack's oceanfront lots and preserved farm parcels are among the scarcest and most valuable in the country, which is why the village so often tops "most expensive ZIP code" lists. Water Mill offers a broader range: grand oceanfront and estate-section homes to the south, and more attainable (by Hamptons standards) properties near the bays and farmland to the north.
If you are weighing one of these communities, the practical questions come quickly: How close is the ocean? Is the property in the estate section or north of the highway? What are the flood and zoning considerations near the ponds and bays? How does the tax picture compare between an incorporated village like Sagaponack and a hamlet like Water Mill? Those are exactly the details that separate a good Hamptons purchase from a costly mistake, and they are worth talking through with someone who works this specific market every day.
