Acadia National Park: This park offers both active and more relaxed ways to enjoy its splendors, and it's accessible by a 27-mile loop road. You can hike, bike or even drive the 0.3-mile paved pathway that encircles Cadillac Mountain to a summit of 1,532 feet -- the highest point on the eastern seaboard of the United States. It is the first spot in the U.S. where the sunrise can be seen, but its 360-degree views can be enjoyed all day long.

Thunder Hole: Another natural highlight, accessible by the Island Explorer bus (Sand Beach/Blackwoods route). Watch water surge and spout as high as 40 feet with a thunderous boom as waves rush into a small inlet, naturally carved out of the rocks.

Cooking Classes: Learn to recreate classic Maine dishes at home. Le Cordon Bleu-trained chef Sharon Joyce offers cooking classes that focus on local specialties like lobster, blueberry muffins, chowder and popovers at her Ambrosia Cooking School.
