Huntington Bay sprawls inward from Long Island Sound. It is the largest of the Long Island harbors and marks the beginning of Suffolk County. Nassau County is to the west.

Huntington Bay narrows as it goes south and then spreads out to the east, west and south into seven separate, sheltered, inner harbors lined by the villages of Huntington, Centerport and Northport. Boating amenities are everywhere. There are many anchorages–some crowded, some isolated–plus good beaches and fine restaurants.
