Boston's enormous role during the American Revolution is inescapable, and it's easy to trace by following the Freedom Trail, which links more than a dozen historic sights throughout town from the Paul Revere House to the Old North Church. But don't forgo exploring Boston's appealing modern side. For a 360-degree view of the city, head for the skywalk observatory on the 50th floor of the Prudential Tower. For art, browse the Museum of Fine Arts, which includes works from Van Gogh to Egyptian sculpture. If your interests lie in the natural world, wander through the remarkable New England Aquarium or Franklin Zoo.
