Visit the iconic Tower of London and marvel at the crown jewels. You can also explore the Gothic-style Tower Bridge nearby. Opening time varies during the year so check before you go.
Spend the day in Covent Garden browsing the shops and street performers. Catch one of the many shows available in the West End, such as the Mousetrap or Phantom of the Opera. Leicester Square and Soho have many dining options for dinner.
Marvel at the Gothic architecture of Westminster Abbey and then take a walk down to the Houses of Parliament. If you have the time, go on a tour or watch a debate at the House of Commons. Open 9:30 am - 3:00 pm on select days.
End your trip with a visit to The Tate Modern museum and its contemporary art collections. Cross over the Millennium Bridge for a great view of the Thames River and visit the Shakespeare's Globe Theater nearby. Closing time varies during the year so check before you go.
