Threemile Harbor
Threemile Harbor is a well-protected anchorage tucked into the southern end of Gardiners Bay, about three miles from the village of East Hampton — that's actually how it got its name, not from any measurement of the harbor itself. You'll find calm, sheltered water here with a genuinely quiet, local feel that sets it apart from the busier Hamptons scene nearby. The Springs area surrounding the harbor has a long history as an artists' community, and East Hampton's shops, restaurants, and galleries are just a short trip away.
