Horse Guards Parade
Horse Guards Parade is located in the centre of the borough of London, near St. James's Park, Buckingham Palace and 10 Downing Street.
Horse Guards Parade is a parade ground near Trafalgar Square where the Changing of the Queen's Life Guard occurs daily at 11 am, and 10 am on Sundays. In the Guard Change, two cavalries arrive at the courtyard, where one starts their guard duty and the other return to the barracks. The guards have formal wear, one group in red and the other in blue tunics.
After the change, the soldiers ride under the Horse Guards building. The change occurs in an open, unfenced area so that you can follow it from quite a close distance.
At the front of the building are two guards on horseback, where many tourists typically take pictures of them. The horses are docile, but there is a sign on the wall nearby warning from going too close.
In the area, you can also find guard-related parades, where the Queen or Prince Charles check the troops.
The nearest station is Charing Cross, roughly 5 minutes (Bakerloo, Northern) and Embankment (Bakerloo, Northern, District, Circle) roughly 10 minutes away.
Travelling by train to Charing Cross is also the same distance away.
