Buckingham Palace: Our Tips. When to See the Changing of the Guards. The changing of the guard takes place everyday at 11:30am from April through July, and on alternate days the rest of the year. Due to its popularity, the changing of the guard attracts massive crowds. If you want to secure a spot near the fence to get the best view of the spectacle, it's necessary to show up at least a couple of hours in advance.
