Maine’s Acadia National Park is marked by woodland, rocky beaches, and granite peaks carved by the Atlantic Ocean; plus, it’s home to moose, bears, whales, and seabirds. Hike or drive to the top of Cadillac Mountain—the tallest peak on the East Coast—to catch the first sunrise in the U.S. Afterward, head to Bar Harbor to try the country’s (maybe world’s) best lobster.
