Three Mile Harbor
Three Mile Harbor is a protected coastal harbor in the Town of East Hampton on the South Fork of Long Island. Opening into Gardiners Bay, the harbor is known for recreational boating, sailing, fishing, marinas, waterfront dining, marine businesses, and scenic sunsets.
The harbor extends inland from Gardiners Bay and is surrounded by residential shoreline, tidal wetlands, docks, restaurants, resorts, and marine facilities. Its sheltered location has made it an important part of East Hampton’s maritime character and one of the better-known boating areas in the East End.
Where Is Three Mile Harbor?
Three Mile Harbor is located northeast of the Village of East Hampton in Suffolk County. It lies within the broader region commonly known as the Hamptons and opens northward into Gardiners Bay.
The harbor is reached by land primarily from Three Mile Harbor Road and nearby local roads connecting the waterfront with East Hampton and surrounding sections of the town. By water, its entrance provides access between the protected harbor and Gardiners Bay.
From Gardiners Bay, boaters can continue toward Shelter Island, the North Fork, and other destinations around eastern Long Island.
History of Three Mile Harbor
Three Mile Harbor has long been connected to the maritime history of East Hampton and eastern Long Island. Its protected waters provided anchorage for fishing boats, local vessels, and mariners traveling between communities around Gardiners Bay.
Fishing, shellfishing, boatbuilding, and other marine trades contributed to activity around the harbor. These industries formed part of a wider coastal economy that developed throughout the East End, where harbors and bays provided transportation routes, food resources, and access to surrounding waters.
Although recreational boating now accounts for much of the harbor’s seasonal activity, Three Mile Harbor continues to retain elements of a working waterfront. Marine businesses, docks, fishing vessels, boatyards, and related services remain part of the harbor’s identity.
Boating and Marinas
Three Mile Harbor is one of the principal recreational boating areas in the Town of East Hampton. Several Long Island marinas and marine businesses operate along or near the harbor, providing services that may include seasonal dockage, transient slips, fuel, storage, repairs, launching, and vessel maintenance.
The harbor’s protected shape generally offers calmer conditions than the open waters of the Atlantic Ocean. Sailboats, fishing boats, pleasure craft, and larger yachts can frequently be seen traveling through or anchored within the harbor during the warmer months.
Boaters considering a visit can review the site’s guides to boat slips and marinas and boating and boat rentals on Long Island. Navigators should remain aware of marked channels, tides, weather, speed restrictions, and local harbor regulations.
Fishing and Shellfishing
Fishing remains an important recreational activity in Three Mile Harbor and the adjoining waters of Gardiners Bay. Depending on the season and location, anglers in the surrounding area may pursue striped bass, bluefish, fluke, porgy, weakfish, black sea bass, and other coastal species.
The harbor’s shallow water, tidal shoreline, wetlands, and sheltered coves also provide habitat for shellfish and juvenile marine life. These ecological areas contribute to the productivity of the wider Gardiners Bay system.
Anyone planning to fish should review current state and local regulations, including seasonal closures, size limits, possession limits, and registration requirements. Long Island Guide provides additional information about fishing on Long Island, places to fish, fishing license requirements, and charter fishing boats.
Kayaking and Paddleboarding
The harbor’s generally protected waters make it popular for kayaking, canoeing, and stand-up paddleboarding. Paddlers can explore portions of the shoreline, tidal coves, marshes, and quieter sections located away from the busiest marina areas.
Three Mile Harbor can offer a more sheltered experience than paddling directly along an ocean beach, but conditions are not always calm. Wind, tides, visibility, weather, wakes, and motorboat traffic can all affect conditions on the water.
Paddlers should use personal flotation devices, remain visible to vessel operators, avoid obstructing navigation channels, and check conditions before launching. Additional locations and planning information are available through the guides to kayaking on Long Island and stand-up paddleboarding.
Waterfront Dining, Resorts, and Events
Three Mile Harbor is known for seasonal restaurants, marinas, resorts, and hospitality businesses overlooking the waterfront. Some properties provide outdoor dining, dock access, accommodations, private gathering spaces, and views across the harbor.
EHP Resort & Marina is one of the harbor’s prominent waterfront properties. The resort includes marina facilities and hosts dining, private functions, and special events beside the water.
The combination of harbor scenery and waterfront hospitality makes the area part of East Hampton’s summer tourism economy. Readers seeking similar experiences can explore the guide to waterfront restaurants on Long Island and the site’s broader directory of restaurants.
Wildlife and Coastal Habitat
Three Mile Harbor and its surrounding wetlands support fish, shellfish, shorebirds, waterfowl, and other coastal wildlife. Ospreys, herons, egrets, ducks, gulls, and migratory birds may be observed around the harbor at different times of the year.
Tidal marshes and shallow shoreline areas provide feeding, spawning, and nursery habitat for marine species. These natural areas also help support the environmental health of Gardiners Bay and the surrounding East End coastline.
Visitors interested in observing coastal wildlife can also consult the guide to birdwatching on Long Island. Wildlife should be viewed from a respectful distance, particularly around nesting areas and sensitive wetlands.
Sunsets and Harbor Views
Three Mile Harbor is especially known for evening views across its marinas and sheltered water. Sailboat masts, docks, anchored vessels, and reflections on the harbor create a distinctive setting as the sun lowers over East Hampton.
The harbor’s western-facing viewpoints and waterfront properties make sunset one of the most scenic times to visit. Other locations for evening scenery are included in the guide to the best sunset spots on Long Island.
Access and Seasonal Conditions
Access to the Three Mile Harbor waterfront varies by location. Much of the shoreline is occupied by private residences, marinas, restaurants, resorts, marine facilities, and protected habitat. Visitors should use authorized public access points and respect posted restrictions, private property, marina rules, and parking regulations.
Activity around the harbor is greatest during late spring, summer, and early fall. Conditions are quieter during winter, although year-round residents, marine businesses, and working vessels continue to use the area.
Weather can change quickly around eastern Long Island. Boaters and paddlers should review the Long Island weather forecast before heading onto the water and remain alert for strong wind, thunderstorms, reduced visibility, and changing tides.
