If you find yourself in the room with the old fire rings and bamboo door, don't spend time looking for a way to open the door. It's not going to open. Falling off the bridges won't kill you, but it will set you back a little bit. You want to be up there. Towards the end there's. A hallway with a large stone door at the end and lots of darts. You'll notice when you come down to the floor level there's no way to climb up to the other side. If only there were a place to jump across the top.
