Threemile Harbor

Threemile Harbor is a well-protected anchorage tucked into the southern edge of Gardiners Bay, making it one of the more sheltered spots you'll find along this stretch of Long Island's East End. You're dropping the hook in Springs, a quiet, artsy hamlet with deep ties to the abstract expressionist movement — Pollock and de Kooning both lived nearby. The surrounding marshes and wooded shoreline give it a genuinely unhurried feel, and you're within easy reach of East Hampton if you want to explore inland.
