If Bar Harbor seems like a scene out of a landscape painting, that’s because it is. The picturesque Maine fishing town attracted the Hudson River School painters in the mid-1800s. Today, it's a popular vacation spot and port for New England cruises (large ships anchor offshore, and passengers are tendered to port). The enchanting downtown is easily accessible by foot from the cruise port, or you can book a lighthouse cruise or a nature excursion to Acadia National Park.
