Acadia National Park is an American national park located along the mid-section of the Maine coast, southwest of Bar Harbor. The park preserves about half of Mount Desert Island, part of the Isle au Haut, the tip of the Schoodic Peninsula, and portions of 16 smaller outlying islands. It protects the natural beauty of the rocky headlands, including the highest mountains along the Atlantic coast. Acadia boasts a glaciated coastal and island landscape, an abundance of habitats, a high level of biodiversity, clean air and water, and a rich cultural heritage.
The park contains the tallest mountain on the Atlantic Coast of the United States (Cadillac Mountain), exposed granite domes, glacial erratics, U-shaped valleys, and cobble beaches. Its mountains, lakes, streams, wetlands, forests, meadows, and coastlines contribute to a diversity of plants and animals.
There are two campgrounds on Mount Desert Island, one campground on the Schoodic Peninsula, and five lean-to shelters on Isle au Haut. There is no backcountry camping, “out-of-bounds” camping, or overnight parking allowed anywhere in Acadia.
