How do you catch Dialga/Palkia and Heatran in pokemon platinum.

k so how to catch them s that, you first have to beat the elite 4 and recieve ur national dex. Then fly to Hearthome city and go to Mt. Cornet (must have pokemon that know Rockclimb, surf, and maybe strengnth)once in Mt.Cornet, surf and walk your way around till you get to stairs.Go up and walk ur way round all the crap till u reach a hole in the wall. Go in and walk round till u find stairs. Go up and then go straight up and continue that path till u find a cave leading outside. Once outside,walk up and then down stairs till u see rocks where u can use rockclimb.Use rockclimb once and then walk 2 ur right till u find a cave leading inside. Once in,go straight till u see water. Then surf and use waterfall and go into the cave on the top inside lies the 2 orbsto recieve Palkia and Dialga!! To get Heatran, fly to the servival area and go right till ur at route 226 (u need pokemon that know rockclimb and surf)go up the first rockclimb and down the one to ur right. Walk through the grass till u see the next rocks to climb. Keep walking and go down the first pair of rocks.Keep walking till u arrive at an ocean. Surf till u arrive at grassy land. Go straight up till it starts to snow ashes and then take ur bike out. Those light brown piles,quickly run over them with ur bike till u reach stairs. Go up and take out ur bike once more and follow the mud path. Go straight through grass then down till u reach and go up stairs.G through grass and go down some stairs till u arrive at a cave. Once in, explore till u find a cave and Heatran will be inside. (Need a master ball to catch it) Hpe i helped ad hope th pokemon will bes good to u as there are good to me!!!

to catch Dialga/Palkia, you have to first beat the elite four. then, you go back to spear pillar and then near the part where you saw dialga and palkia should have to blue and pink stripe things. you go up to them and press A to fight and catch them. Now, for Heatran, you have to first
1or2. beat the elite four and get the national dex. whichever comes first.
3. go to the stark mountain , which is at the island at the top right part of the map. on the way there you meet this red haired dude that also wants heatran.
when you get to stark mountain, you meet up with him and barry and Wake (the gym leader). after the dialogue you go into stark mountain.
4. when you get in, you have to push around all of these boulders to get through to the next part. takes up some time.
5.when you get to the next part. you see the red haired dude again. he's having trouble getting through and wants you to help. on the way through you have to battle some trainers.
6.when you get through there. there's a clearing with these stones in it, with one in the center.
the red haired dude runs in, takes the stone in the middle, gloats, and runs out. well, turns out that you have to go chase him back to his house at the survival area, which is at the top left part of the island you're on.
7.you get to the survival area. you go to the house on the top left part of the survival area, go in, talk to the old man, there's some dialogue,
and the red-haired dude goes back to stark mountain to put the stone back. so, you have to go all the way back to stark mountain (again!!!).
8.you go to stark mountain, go to the last part of it(you should know the way). and you noticed the red-haired-wonder isn't there. but in the middle of the stones is..................................................................................................

HEATRAN!!!!!!!!!


btw, the first comment is wrong. it's harder, but you don't need a master ball to catch palkia, dialga, or heatran.
