Acadia National Park is open all year long. However, this does not mean that all facilities and roads are open and accessible. The Park Visitor Center, museums, picnic areas, Seawall Campground, and many of the roads close during the winter. The road to the summit of Cadillac Mountain, as well as most of the Park Loop Road, closes from December 1 through April 14. Some sections do remain open as weather permits.
Two short sections of the Park Loop Road remain open all year. One
is a scenic one-mile section along the ocean that goes by Sand Beach and Thunder Hole, accessed via Schooner
Head Road, two miles south of Bar Harbor. The other gives access to Jordan
Pond via the Jordan Pond Road in Seal
Harbor. For additional information, contact the National Park Service directly or visit their Temporary Closures page for recent postings.
