They were really majestic. This wonderfully groomed horses, their proud riders… If they represent the queen and her honorable position, they truly do a great job… We don’t have something like that in Germany and watching them parade was a really special moment…
They start around 11 o clock I think (i have no idea) and it is really crowded, if you arrive late… maybe look for some places at the far end of the square, the horse guards position themselves in two rows, facing each other, so no matter where you stand, you’ll see enough for pictures and appreciating the momentum.
there will be a long period where nothing happens, they just stand and wait. Remain close to the square, wait until the move on, because it looks wonderful when they leave.
BUT: NEVER blockade the exit. Never. A few other tourists did and the mounted police got really annoyed, shouting, whistling… Just never do it. You don’t want to be the idiot they shout at (because everyone will look at you with an ‘oh-that-poor-idiot’- expression.)
