well, it depends on what you mean by 'get past' if you mean get through the cave, then you can't. the cave dosent have a ending. it just does on and on... if you mean getting to giratina... im not sure exactly how to get to em, but i do know that if you keep moving into different rooms, you can eventually find it. if i didn't answer your question...then this link may help http://bulbapedia.bulbagarden.net/wiki/Turnback_Cave btw, to get out of turn back cave, just go through the southern door. it will take you back to the first room no matter how many rooms you have past. how I've helped.

Turn back cave is located at sendoff spring along the spring path. You get teleported here after you escape the torn world. You can't access it until you get the National Dex though.
Go to the room with the third pillar. There should be a portal in front of the item that you get depending on the amounts of rooms you have been in (if you haven't gotten it yet).
