If you are in London, yes. It is a must see. Not going would be like going to Disney, and not seeing the castle. When I went, there were lots of people, so it may be good to get there early so you will be able to see. Also pay attention to what flags are flying above the palace, they will tell you where the queen is.
Seeing the changing of the guard at Buckingham Palace is one of those must-see events when in England. The guards have been protecting the palace since 1660, and this is part of our world's amazing history. Just as people see landmarks, nature and try various foods, seeing the changing of the guards should not be passed up!
I have been lucky enough to travel to England twice. The first time we were there, we made sure we saw the changing of the guard at Buckingham Palace. It was a delight to see. I would highly recommend that any visitors to London make time to see this. The whole ceremony gives you a real sense of how the English people feel about their monarchy. It is also just fun to watch!
The changing of the guard at Buckingham Palace is a longstanding tradition, but it is not very exciting whatsoever. The whole ceremony is meant to glorify the long-lost remains of a dying monarchy and has no relevance today. While the people who perform the ceremony are pretty chill overall, it has no importance. You don't need to see it.
The changing of the guard at Buckingham Palace is a nice to see, but definitely not a must see. It's nothing more than a few guards going through an old tradition. Beyond that, it's a waste of time. It's definitely not worth hours waiting to see. Go to the internet and watch it if you want to.
