A passage that couldn't be seen before the flood of 2068-69 is now perfectly visible to all. Headmaster Bontecou once repaired it so that it no longer goes very far, but it does take you indirectly to the entrance of the Slytherin Common Room...if you aren't a Slytherin. If you are one, you'll see a new track that turns right to lead you to your common room - just what you need when you forget the password.

The passage may be dark and winding, and can occasionally smell like sewage (thanks, Myrtle), but that's no excuse for snogging down here!
