Visited in 2017, pictured are shots from Bar Harbor ( Ba Haw Ba), Camden, Acadia National Forest and the top of Cadillac Mountain. Maine, the northeasternmost U.S. state, is known for its rocky coastline, maritime history and nature areas like the granite and spruce islands of Acadia National Park. Moose are plentiful in Baxter State Park, home to Mt. Katahdin, endpoint of the Appalachian Trail. Lighthouses such as the candy-striped beacon at West Quoddy Head, dot the coast, as do lobster shacks and sandy beaches like Ogunquit and Old Orchard.
