New York City
New York City is one of the world's most famous cities. Despite its image as a place of extreme hustle-and-bustle, it is becoming a better and better city to explore on foot. First of all, the public transportation system (including the iconic New York subway) makes it simple to get around without a car (or a taxi). Wherever tourists find themselves in the Big Apple, chances are there is a subway station within a block or two. Another NYC icon, Times Square, is now a pedestrian area, and, of course, neighborhoods in every one of the five boroughs are filled with shops and buildings that make for some great off-the-tourist-trail sightseeing. New York's pedestrian crossings are well-organized, making it pretty straightforward to cross even busy major thoroughfares. Another plus: Streets are numbered logically, so getting lost, even if you left your map at the hotel, is difficult to do.
