How do you get Giratina in Pokemon pearl?

Answer 1

turn back cave
you go to spring path and go through but you will want repels and rock smash.

You can only obtain Giratina in Pokemon Pearl after defeating the Pokemon league and after obtaining the national Pokedex. Make sure you have the HM's Rock climb, Defog, Rock smash and fly (to travel to Veilstone city) also 4-5 max repels (unless you want to battle wild Pokemon) and many Dusk balls and Ultra balls (save your Master ball for Arceus, once you have the Azure Flute).

To obtain Giratina in Pokemon pearl travel south from Veilstone city (route 214) continue south until you see an opening/entrance between two trees. (This opening/entrance is to the left of Ruin Maniac Hunter who has a level 26 Shieldon) continue down the opening/entrance and you will be on the 'Spring Path'. Continue on 'Spring Path' and you will be on 'Sendoff Path' and across the large grassy patch. You will notice there is a wall that is very rocky, rock climb on it and travel around the round path until you reach an area of trees and another wall that is very rocky, you will notice that there is a cave entrance. Rock climb down the wall and enter Turnback cave's entrance. Once you have entered Turnback cave use defog. You will notice there is a wall in front of you, click on it and written on it is "...Past three pillars ... offer up ... to the... ...before 30 is surpassed..." Travel around the wall and continue through many rooms, you can travel forward, left or right, but don't go backwards as it takes you to the room where you entered Turnback cave (they are all the same room, but the rocks are in different positions or patterns) continue past 3 pillars until you reach a large room and there standing in the middle is Giratina. Giratina is level 70 with the moves Shadow force, Slash, Earth power and Shadow claw. Save before you battle Giratina, just to be on the safe side. After you capture Giratina collect the Pokeball (Rare bone), behind the Rare bone is some writing on a wall. It sez "This is ... That where life sparkles ... That where life has faded ... A place where two worlds overlap ..."and leave via any door way.
