London in a day: So you’ve only got one day in London and want to see everything. You can do it. By walking about 20km you can see as many of the classic tourist sites as possible. Buckingham Palace, London Eye, Tower Bridge, Tower of London, squirrels, deck chairs and ducklings in St James Park, Westminster Abbey, St Paul’s Cathedral, Millennium Bridge, Big Ben (covered in scaffolding 😔) and Trafalgar Square. Ending your day with a London West End Show that we decided to do at 3 o’clock that day! You won’t have time to go inside the sites though. Just grab a photo and a look. Perfect
