Once you arrive in London, start your first day at the true heart of the city – Trafalgar Square. The most famous tourist attractions follow on your itinerary: London Eye, Big Ben and Buckingham Palace. You can finish your day in one of the great museums. Take a little rest from the lively city on the second day, head to the Windsor Castle and take a walk in the Greewich Park afterwards. On the third day, your London itinerary takes you to the landmarks in the center again: the Tower with Tower Bridge next to it and St. Paul's Cathedral.
