Isle au Haut, Acadia National ParkFar from the crowds of Mount Desert Island and the tourist town of Bar Harbor, a remote section of Acadia National Park can be found on the smaller island of Isle au Haut. Located roughly 15 miles southwest of Mount Desert Island as the bird flies over the ocean, a visit to the island is via the mailboat out of the town of Stonington. Roughly half of Isle au Haut consists of private residences, but most of the southern part of the island is designated national park land. Visitors should be respectful of private property boundaries and should be sensitive to the fact that people live and work here; the island isn't just a recreational getaway for tourists.

Acadia National Park on Isle au Haut is primitive with several strenuous trails that explore the rocky cliffs and coves of the coast as well as the inland forests and peaks. But aside from the ranger station near town and the pit toilets at Duck Harbor, there are no tourist luxuries or amenities whatsoever. A visit to Isle au Haut is for the lonely wandering soul who is looking to explore beautifully rugged and remote scenery. This is not a place for the casual tourist.

Getting to Isle au Haut:

The first task is to drive to Stonington to pick up the mailboat. If driving from Bar Harbor, it's a 60-mile drive and you should allow 1.5 to 2 hours, depending on traffic. Take Route 3 off of MDI to Ellsworth, and then take Route 172, Route 176, and Route 15 southwest for roughly 45 miles. Near the village of Sargentville, turn right to stay on Route 15 and cross over the impressive Deer Isle Bridge. Route 15 continues south another 22 miles and ends in Stonington at the southern tip of Deer Isle. Isle au Haut is five miles to the south behind many smaller islands.

Isle au Haut, Acadia National Park


Camping is permitted only at the Duck Harbor Campground located just to the west of the boat landing. Five primitive campsites are available for reservation in advance; no walk-ins are permitted. (See the NPS website for details.) Each site has a fire ring, a picnic bench, and a small lean-to shelter that can accommodate 1 or 2 small tents. (Dead and down wood may be collected for campfires.) Two pit toilets are available onsite, and drinking water is available from a pump well located along the dirt road .2 miles east of the campground.

IMPORTANT: Every visitor to Isle au Haut must utilize their best "leave no trace" skills. Please do not go to the bathroom in the bushes close to your campsite; use the pit toilets at the entrance to the campground. Pack out all trash with you and leave your lean-to shelter spotless for the next group to enjoy.
