Three Mile Harbor Professional Guide

Detailed Trail Description from our Guidebook

"A great place for seeing a variety of birds—including rare species, Three Mile Harbor features egrets, osprey, oystercatchers, plovers, terns, herons, and dunlins—and diamondback terrapins.

Three Mile Harbor is a beautiful, large protected harbor off of Gardiners Bay. It is east of Sag Harbor (about 3 miles from East Hampton) and is East Hampton’s most popular port. Three Mile Harbor offers boaters convenient access to anchorages, marinas, supplies, and restaurants.

At the entrance to Three Mile Harbor, from Gardiners Bay, is a narrow inlet bordered by two parks. On the western side is Sammy’s Beach, a 116-acre nature preserve that separates Gardiners Bay and the Three Mile Harbor Inlet. This approximately 1-mile-long spit of land provides habitat for roughly 50 types of birds, including some rare species. The preserve is one of more than 400 nature preserves that encompass 3,500 acres of land in the town of East Hampton."
