Maine’s most famous national park site is Acadia National Park. Though smaller than the massive National Parks found out west, Acadia is one of the top 10 most-visited national parks in the United States. It includes stunning views of the ocean, 158 miles of hiking trails, 27 miles of historic motor roads, and 45 miles of carriage roads.
But Acadia isn’t Maine’s only NPS site. Katahdin Woods and Waters National Monument protects the stunning landscape surrounding Mount Katahdin, the Frances Perkins National Monument protects the homestead of the first woman to hold a presidential cabinet position, and the Appalachian National Scenic Trail comes to an end (or starts in) in Maine.
Arguably Maine’s most unique NPS site, however, is Saint Croix Island. It is the only International Historic Site in the U.S. as it’s shared with Canada. It protects an area once home to one of the earliest attempts to establish a French settlement in North America. Despite its inclusion in the service, however, Saint Croix Island is off limits to the public in order to protect its historic sites.
