Bridgehampton is immediately west across Sagg Pond and is where Sagaponack residents do most of their shopping and dining; the two are reported together in market data. Water Mill lies beyond it and is grouped in the same reporting. Wainscott is immediately east across Town Line Road, in the Town of East Hampton, which means a different town, a different school district, and a different beach permit. Sag Harbor Village is about fifteen minutes north and is the nearest walkable downtown. Each has a full guide on this site.
