There are many ways to get around London, my favorite being the subway, or the Tube. It is the cleanest, most extensive, and best managed system that I have ever been on. When you get on or off the tube, a recorded voice reminds you to "mind the gap." A scenic way to get around is on a cruise on the Thames river, especially at night. The city is lit with its most famous landmarks in their full splendor. Of course they are also regal during the day.
