Acadia National Park Fact Sheet


Acadia National Park protects a scenic landscape of coastal islands and glacially sculpted mountains rising from a bold rocky Atlantic coastline. The park offers visitors a broad range of experiences through a designed network of historic carriage roads, hiking trails, and motor roads interwoven through a mosaic of diverse ecological systems. Acadia is the oldest eastern national park and the first national park created from private lands gifted to the public through the efforts of conservation-minded citizens. The park supports and benefits from a continuing legacy of more than 100 years of scientific investigation.

Acadia National Park’s weather is largely a product of latitude and marine influences. Precipitation occurs in every form. Rain falls in every month with an annual average of 48″. The park also has a respectable annual average of 61″ of snow. The tempering maritime conditions, however, with frequent freezing and thawing, prevent large, long-term accumulations. On a daily and annual basis, Maine temperatures are more severe inland than they are on Mount Desert Island and on the coast in general.

Scenic Drives

The Park Loop Road: A 27-mile paved road carries visitors through some of the most beautiful features of the park. The road affords views of the Gulf of Maine and Acadia’s rocky coastline, winds through quiet woods and around mountains, past large glacial lakes, and ascends Cadillac Mountain. Favorite destinations along the Loop Road include Sieur de Monts, Sand Beach, Thunder Hole, Otter Cliffs, the Jordan Pond House, and the Cadillac Mountain Summit.

Westside of Mount Desert Island: Just south of Southwest Harbor, Route 102A provides access to another coastal section of Acadia National Park. Sites of interest include a natural seawall, Seawall Picnic area, Seawall Campground, Wonderland and Ship Harbor Trails, and the Bass Harbor Head Lighthouse.

Schoodic Peninsula: 1.5 hours “downeast” of Bar Harbor, Schoodic is the only part of the park located on the mainland. The 7-mile one-way loop road offers views of the rugged coast.

Sargeant Drive: In addition to the Park Loop Road, state and county roads offer scenic views. Sargeant Drive skirts the edge of Somes Sound. Access is from Northeast Harbor or off State Route 198.
