While urban areas populate the state of Maine, particularly along the eastern coast of the Atlantic Ocean, there are vast wilderness areas across the state, even along the oceanside coast. Popular with tourists, the state and local economies benefit from an influx of $8.2 billion in outdoor recreation dollars. Acadia National Park, called the Crown Jewel of the North Atlantic Coast, draws 4 million visitors annually, ranking in the top ten most-visited national parks in the United States. The park features 27 historic roads, 158 miles of hiking trails, and 45 miles of carriage roads.
