Part of the charm of visiting London, one of Europe's biggest and oldest cities, is just taking the time to walk the street and explore. And with so much to see, this could definitely take you hours, no days, to see it all. There were some highlights we wanted to hit on our mini-tour of London: Trafalgar Square, Piccadilly Circus, the Changing of the Guards, Buckingham Palace, the banks of the Thames, Big Ben. And, we managed to actually see them all!
