Where to catch Dialga and Palkia in Pokemon platinum?

Answer 1

To find Dialga and Palkia in Pokemon Plaltinum, first you need to get the marking map poketch app from the president of the poketch company in Jubilife city. Then you need to get all the legendarys of the lakes. (Uxie, Azelf, Mespirit) Uxie and Azelf are hard enough to catch while mespirit is three times as hard to catch. It flees as soon as possible, It flies all over the sinnoh region (that is why you got the marking map). Then go defeat the elite 4 and the champion. Next and all the legendarys to your party and go to the ruins and talk to cynthia's grandmother and then go to spear pillar. Dialga and palkia are lv70 so be prepared to catch them. Go to the end the place(near the whirlpool that Giritina created) and you'll find a floating blue diamond and talk to it and you fight dialga! After you have fleed, defeated or caught Dialga, exit and go back and there will be a floating pink diamond and repeat the process.
