Acadia National Park dominates much of Mount Desert Island. It covers more than 40,000 acres or about two-thirds of the island. Opened in 1916, the park also extends beyond Mount Desert Island.

You’ll find the park is a feast of natural sights. Native plant, land and marine mammals , birds and waterfowl thrive on the shore, woodland and mountain regions. You can travel the park on propane-fueled buses free of charge.
