Dialga is not behind the waterfall all that is there is Dratini and Dragonair You find Dialga in a hidden cave in the wall on the east side of it. Love to answer your questions!!!!!
After you catch giratina,I'm pretty sure there will be two ovals,one pink and one blue,the blue oval contains dialga and the pink one contains palkia you need the adamant and lustrous orb if you have them click on the oval and they will show up!
you go to celestic town ad go to to one of the houses nearest to the cave, talk to a the lady in the house she will show u a picture of dialga and then u have it
If it is in Pokemon Platinum, after you get Waterfall, go inside a cave and use Waterfall. There is a mini cave. Go in, and there is two items. they are the Admant and Lustrious orbs. They are not in Diamond and Pearl. Keep the items in your bag, go to Spear pillar, and Dialga and Palkia's portals are there. First there is a blue portal. Talk to it. Dialga's in there. Say yes to the question, and you will battle it. Once you finish the battle, go outside Spear pillar, then come back in. There is a pink portal, and Palkia's in there. Good luck!
Go to the top of Mount Coronet, using the cave system from Hearthome's side. Once you have reached the top, you will find Team Galatic's Boss's waiting for you, and they will challenge you to a fight. When you have beaten them, and have beaten the final boss, you can catch Dialga/Palkia (depending on whether it is diamond or pearl).

well, you have to have the lustrus and admant orbs, or else you cant. To get the orbs, go to mount cornet and when you go into an outside and you have to go to your right after using rock climb once and There's a a cave. Go in it and use surf and waterfall. Then you'll see another cave with 2 poke-balls in it. Those are the orbs. then make your way back up to spear pillar and when you get there, you ill see a portal. The first summons Dialga and the second summons Palkia! after summoning dialga, go back through the cave you entered and go to the left of where dialga was, and theres a pink portal press the a button by in to summon Palkia! hope i helped Gliscor 675 signing off!
You can't get Primal Dialga, but you can get normal Dialga after you beat the cave (Lapras will always be at the beach and you can ride him to go to Hidden Land any time)
actually you can get dialga AND palkia without an action replay and how to do that is this... go to mnt coronet and go the cave with the dark little cave and the orbs will be in there after you pick them up go to celestic town and talk the old woman in the house above the cave, after that go to the spear pillar and there will be a blue little spot, talk to it and you will battle dialga, turn around and go back into the cave, then go right back to the spear pillar and there will be a purple spot, talk to it and you will battle palkia. HOPE THIS HELPS
