Turnback Cave

In Diamond & Pearl, the Turnback Cave can be found by going to Sendoff Spring, which is past a place called Spring Path. The player can only go to Spring Path if they've gotten their National Dex. To get there, you must go to Veilstone City. Then, you go to the south exit, which is Route 214. Go down a bit, then go to the little opening you see to the east. Run east and north on that path until you reach Sendoff Spring. There are two places to use Rock Climb. Go to the one east of the two trees. After using Rock Climb, go across and back until you reach another place where you can use Rock Climb, then go down there, and go in the cave, and you're in. Turnback Cave is home to the legendary Pokemon, Giratina.' In Platinum, after beating or catching Giratina in the Distortion World (excluiseve to you Platinum), a portal will bring to Sendoff Spring. Untill you beat her, Cynthia will be blocking the enterance' to the Turnback Cave. If Giratina got KO in the Distortion World, it will reapear here.
