Acadia National Park has three wooded campgrounds, all within a five-minute walk of the ocean. Two are on Mount Desert Island and one is on Isle au Haut. Additional camping facilities are located outside the park.

Blackwoods Campground

Blackwoods Campground is located off of Route 3, five miles south of Bar Harbor on the eastern half of Mount Desert Island. More than 300 campsites are open.

From May 1 to October 31, reservations are suggested and sites cost $20 a night. All major credit cards are accepted. Reservations can be made six months in advance. For more information visit recreation.gov. Winter camping is by permit only and facilities are limited.

Seawall Campground

Open from mid-May through September, Seawall Campground accepts reservations for half of its sites, and the other half is available on a first come, first-served basis. Camping is $20 a night with reservations or $14 a night for the many walk-in sites. Although Seawall has more than 200 campsites, it’s best to arrive early to secure a spot. Seawall Campground is open from May 25 to September 30. The campground is located on the western half of the island on Route 102A, four miles south of Southwest Harbor. Kiosk hours vary.

From early spring to late fall, these two campgrounds provide restrooms with cold running water (but no shower facilities), picnic tables, fire rings, dump stations and centrally located amphitheaters for evening ranger programs. Designated campsites can accommodate RVs up to 35 feet long, but neither campground has utility hookups. Public showers and camping supply stores are located within half a mile of campgrounds.

Duck Harbor Campground

The park maintains five lean-to shelters (which can accommodate up to six people) at Duck Harbor Campground on pristine Isle au Haut. Facilities include a picnic table, a fire ring, a portable toilet and a hand-pump for drinking water. Reservations are required and must be submitted in person at Park Headquarters or be postmarked April 1 or later. There is a $25 special-use permit fee. No dogs are allowed in the campground.

Applications delivered or postmarked before April 1 will be returned without action. Telephone requests are not accepted. Mail applications to: Acadia National Park, Isle au Haut Reservations, P.O. Box 177, Bar Harbor, ME 04609; (207) 288-3338. Applications are also available for download at nps.gov/acad.
