Boston, United States

Historic Boston is a key cruise port for 'fall foliage' trips around New England and the Canadian Maritime Provinces but anytime is a good time to enjoy this friendly, walkable city - dubbed 'The Cradle of Liberty' for its part in the American War of Independence. Learn its fascinating history by following the Freedom Trail or take a subway ride beneath the Charles River to Cambridge, home of the 400-year-old Harvard University. On the other hand, you could simply settle for some world class shopping and lunch with a view of street entertainers at one of the pavement restaurants in the leafy lanes which surround pretty Quincy Market. Or spend your day exploring the city's neighbourhoods; Back Bay - filled with elegant boulevards and imposing brownstone mansions - is the trendiest district while North End displays Boston's colonial charm at its best.
