Biking in Maine, whether on the roads or on wooded trails, is a great sport done in beautiful surroundings. Head up to Bar Harbor to bike through Acadia National Park, or down from Kittery toward Floria along the East Coast Greenway. Trails are plentiful, people are friendly, and you can see much more of this incredible state than you would from out a car window. [Photo thanks to John Matrix and Bike List]
