The harbor inlet connects directly to Gardiner’s Bay, just south of Long Island Sound and west of Block Island Sound. This protected harbor features a large deep-water mooring field, a dedicated watersports area, and a fuel dock at Harbor Marina. Three Mile Harbor is ideal for kayaking, paddleboarding, waterskiing, tubing, fishing, swimming, or simply relaxing. The harbor is surrounded by beautiful natural wildlife and wetland preserves, with dazzling sunsets frequently on display. Seacoast Enterprises Associates operates seven transient moorings (500 lbs) in Three Mile Harbor. Guests using the transient moorings have access to the dinghy dock and clubhouse at Three Mile Harbor Marina, which includes bathrooms, showers, grills, and a clubroom with WiFi. A ship’s store on-site offers a wide variety of boating goods. Three Mile Harbor is a no-discharge zone, and East Hampton Town provides a free mobile pumpout service, available on VHF Channel 73.
