About Duck Harbor Campground

Overview

Duck Harbor campsites are reservable starting on April 1st at 10:00am ET. Duck Harbor Campground is located on Isle au Haut, a rugged island off the coast of Stonington, Maine. Remote and inaccessible to automobiles, Isle au Haut is linked to the mainland by mailboat.

Recreation

Isle au Haut offers excellent hiking. The remoteness of the island provides a quiet experience along primitive trails with many great views of rocky cliffs and coastal scenery. Bicycling is allowed but is very rigorous, on loose rock, and unpaved road. No trail biking. You must bring your own mountain bike. Bicycles can only be unloaded at the Town Dock. No bicycles may be loaded or unloaded at Duck Harbor Landing.

Facilities

This small campground contains five campsites. Each campsite has a fire ring, picnic table, and a lean-to shelter which is three-sided with roof and floor. Dimensions are 8' tall, 8' deep, and 12.5' wide. Use of tents is limited to what can fit inside the shelters. There are three composting toilets at the campground. There is a non-potable water source 0.3 miles from campground, however it may not be available during your stay. Plan ahead to bring enough water for the duration of your stay. There is a ranger station 4 miles from the campground but only 0.3 miles from the Isle au Haut Town Landing. The ranger station is open mid-May to mid-October, when there are rangers on Isle au Haut for the season. While the rangers are typically out in the field and not at the ranger station during most of the day, the lobby remains open, allowing visitors access to maps, reading material, and the only public restroom in town. Boat service to Duck Harbor is limited at the beginning and end of the season. Please review the Need to Know section .

Natural Features

Isle au Haut provides opportunities to explore rocky shorelines, wooded uplands, marshes, bogs, and a mile-long freshwater lake. A section of Acadia National Park covers about half of Isle au Haut. The campground is situated on the western side of Isle au Haut. It is just south of the Duck Harbor Boat Landing. The island is approximately six miles long by two miles wide.

Nearby Attractions

There is a small, traditional village near the Isle au Haut Town Landing where one can find a general store, seasonal gift shop, a seasonal food shack, and post office.
