About The

Hamptons

The Hamptons, located between East Hampton Village and Montauk Point, is a coastal and resort Montauk neighborhood with ocean beaches and dune-backed bluffs. The neighborhood’s character concentrates around Montauk Highway at South Elmwood Avenue, where surf shops, seafood counters, and low-key galleries set the pace. Iconic pillars include The Surf Lodge, Gosman’s Dock, and the Montauk Point Lighthouse. Cedar-shingled cottages and modern beach houses sit behind wind-shaped hedges and sandy lanes. Days track the shoreline from Ditch Plains to the rocky edges near the Point. Marinas, farm stands, and seasonal markets keep the calendar tied to the water and fields.
