Acadia is among the top ten most popular national parks in the United States, with more than 3.5 million visits a year. Visitation has surged almost 60 percent in a decade, leading to severe crowding at many park destinations. In 2019, the National Park Service completed a five-year process to approve a comprehensive Transportation Plan that may take a decade or longer to implement fully.
