Start at Green Park with a private guide and walk to Buckingham Palace to watch the Changing of the Guard (daily in June and July, otherwise on Mondays, Wednesdays, Fridays, and Sundays).

Walk down The Mall, a red road bordered by two royal parks and palaces. Head to Parliament Square to see Big Ben and the Houses of Parliament. Pass by Trafalgar Square, Nelson's Column, and Downing Street along the way.

After the walking tour, the guide will direct you to Westminster Abbey with entry tickets provided. This building is significant for coronations and burials of the British Monarchy for over 1000 years. Explore the Abbey at your own pace.

After visiting the Abbey, visit the Churchill War Rooms. Learn about the underground center where Churchill and his team worked during World War II.
