Where is the 7th floor secret passage on Harry Potter and the Order of the phoenix?

Answer 1

Do you mean the room of requirment?

That Harry and the D.A. practice in?

You're supposed to walk by the wall (There's a tapestry of trolls doing Ballet if I'm not much mistaken) three times.

All the while thinking about what you want the room to become.

A door appears.

Unless you're talking about a video game.
Because I'm talking about the book.
