Explore London’s major landmarks and get an overview of the history, culture, and legends of one of Europe’s best-loved cities. Start by heading through Green Park to Buckingham Palace, where on selected days you can watch the world-famous Changing of the Guard ceremony.
After witnessing this impressive traditional ritual, where the New Guard exchanges duties with the Old Guard, head to Westminster. 
Sights you'll see along the way include Downing Street, Westminster Abbey, Big Ben, and the Houses of Parliament. The walk will be timed so that you get to hear Big Ben's globally recognizable chimes.
Then, head to the London Bridge area, where you'll see Shakespeare’s Globe Theater, the Shard, HMS Belfast, Tower Bridge, and the Tower of London.
What makes this tour unique is the expertise and enthusiasm of your guide, who has lived in the center of London for over 20 years (right next to the Tower of London). He is passionate about the history and architecture of the city and really enjoys showing off the city to visitors.
Lots of interaction on this walking excursion will make it a lot more interesting than your average London tour. Your guide has read countless books and attended many talks on London, so they will have many great stories to share.
