The One-Eyed Witch Passage is a secret tunnel that leads from Hogwarts to the cellar of Honeydukes Sweet Shop in Hogsmeade. To gain entrance to the passage, one must give the password; Dissendium. Once the password is given, the witch's hump opens to reveal a short slide into a tunnel which leads under the school and takes about an hour on foot to get to Hogsmeade.
