In the Wizarding World of Harry Potter at Universal Studios, the "secret" entrance to Diagon Alley is cleverly hidden behind a nondescript brick wall in the London waterfront area. To find it, look for a large, curved opening in the red brick wall located just past the Knight Bus and the entrance to the Leicester Square station. Unlike the movies, where bricks physically move, this entrance is a "leak" in the wall that creates a winding, zig-zag corridor. As you walk through, the sounds of the bustling London muggle world fade away and are replaced by the magical music and clatter of Diagon Alley. This transition is designed to mimic the feeling of stepping through a magical barrier. It is remarkably easy to walk right past if you aren't looking for the gap, but once you navigate the short brick labyrinth, the spectacular reveal of Gringotts Bank and the fire-breathing dragon awaits.
