The third-floor corridor was out-of-bounds during the 1991–1992 school year due to the entrance to the Underground Chambers, in which the Philosopher's Stone was hidden, being there, guarded by Fluffy. The door between the Charms corridor and the third-floor corridor was locked, although the Grand Staircase entrance was not, at least for a time.
On the first day of term, Harry Potter and Ron Weasley got lost and attempted to force their way into the third-floor corridor, not realising which corridor it was. Argus Filch spotted them and accused them of knowingly attempting to trespass, but Quirinus Quirrell, who was nearby, had him leave them alone. Some weeks later, Harry, Ron, Hermione Granger and Neville Longbottom hid in the corridor (after Hermione unlocked the entrance on the Charms corridor) from Argus Filch, but quickly left upon seeing Fluffy.
On Hallowe'en, Quirrell attempted to enter the Underground Chambers from the corridor, but was prevented from doing so by Severus Snape, who was bitten in the process. When Quirrell finally succeeded in passing through the trap door, Harry, Ron and Hermione went after him, with Dumbledore eventually following suit.
The third-floor was searched after Sirius Black attacked the Fat Lady. Severus Snape patrolled the third-floor corridor and proved an obstacle to Harry when he planned on using the passageway beneath the statue of Gunhilda of Gorsemoor. Harry used the Marauder's Map and saw that the third-floor corridor was deserted, allowing him to access the passage.
Behind the scenes
- In the first film, Harry, Ron and Hermione access the third-floor corridor from the Grand Staircase, finding the entrance to the corridor, for whatever reason, unlocked.
- In the third game, the third-floor corridor (spelt as the Third Floor Corridor) is simply a long room leading to the Gunhilda of Gorsemoor Corridor, containing several large bookcases.

- ↑ "Even worse than Peeves, if that was possible, was the caretaker, Argus Filch. Harry and Ron managed to get on the wrong side of him on their very first morning. Filch found them trying to force their way through a door that unluckily turned out to be the entrance to the out-of-bounds corridor on the third floor. He wouldn't believe they were lost, was sure they were trying to break into it on purpose, and was threatening to lock them in the dungeons when they were rescued by Professor Quirrell, who was passing."
