"[...] some with a vanishing step halfway up that you had to remember to jump."
—The stairs

These enchanted stairs are staircases in Hogwarts Castle that remove a step halfway up, so you had to remember to jump.

Neville Longbottom regularly forgot to jump the step in one of these staircases. In 1995, Harry Potter made the same mistake after becoming distracted after observing Bartemius Crouch Jr (whom he believed to be Bartemius Crouch Snr) on the Marauder's Map. He became trapped in the staircase and lost hold of his Golden egg clue, which attracted the attention of Argus Filch. The commotion also drew the attention of Severus Snape, who came to investigate, but was supposedly headed off by Alastor Moody, who was the only one that could see Harry in his Cloak of Invisibility with his magical eye. Though Harry did not know it at the time, the man who rescued him was actually the man he had earlier observed on the map.[1]
