The walking tour of all walking tours! - we did a 6 hr walking tour or a 'in one day tour.' They combined Westminster and City of London. Things they covered included St Paul's Cathedral, The Tower of London, London Bridge, Tower Bridge, London Eye, London Monument, River Thames, Buckingham Palace, Changing of the Guard, The Houses of Parliament, Big Ben, Westminster Abbey, Trafalgar Square, The Bank of England - just to name a few. Again, walking tours are such a great way to see a place! Since it was raining and being a Sunday, we decided to grab a pint of beer and a roast at a recommended pub. Yum!!! A good day, enjoyable despite the onset of rain, but that's expected :)
