Acadia National Park

Acadia National Park is a national park of the United States located along the mid-section of the Maine coast, southwest of Bar Harbor. The park includes about half of Mount Desert Island, part of Isle au Haut, the tip of the Schoodic Peninsula, and portions of sixteen smaller outlying islands. 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. Woven into this landscape is a historic carriage road system financed by John D. Rockefeller Jr.

In total, it encompasses 49,075 acres (19,860 ha; 76.680 sq mi; 198.60 km2) as of 2017. Acadia has a rich human history, dating back more than 10,000 years ago with the Wabanaki people. The 17th century brought fur traders and other European explorers, while the 19th century saw an influx of summer visitors, then wealthy families.

Acadia National Park occupies a particular place in the imagination of American public lands. As a National Park in Maine, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
