London: One of the world's best cities for walking

London even wants you to walk. Walklondon.org was established by several governmental agencies with a purpose of getting people off the often-crowded trains and buses and onto the streets. Its website (www.walklondon.org.uk) outlines seven walks. Some cut through the heart of the city; one takes participants along the banks of the Thames; another circles the city. At 78 miles, it clearly isn't meant to be done at once, but in stages, which, after all, is the best way to see London.
