Where do I get Waterfall in Pokemon Pearl?

Question

Do I have to beat the 8th gym leader in order to use it aswell?

And is there another way ot get to Palkia other than going over that waterfall or do I need to go over it?

Answer 1

i believe you will need waterfall. Plus you will have to get one to get to the elite four, both inside and outside of the dungeon.

Answer 2

In Pokemon Pearl, you'll receive HM07 Waterfall in Sunyshore City from Jasmine, a Johto Gym Leader, after you have defeated Volkner:

"Go to the north of the city, where you'll meet Jasmine, a Gym Leader in the Johto Region. She'll give you HM07 - Waterfall." - PokeDream.com

And yes, you need to beat the eighth Gym Leader (Volkner, who specializes in Electric-Type Pokemon, of Sunyshore City) and receive the Beacon Badge in order to use the HM outside of battle, AKA going up or down waterfalls.

As for capturing Palkia, PokeDream.com does very nice job at explaining step by step how to reach and catch Palkia:

You have 2 get Palkia  2 to go 2 Sunyshore City. When u beat the gym leader there, u have 2 go 2 Jasmine @ the beach, and then she will give u the HM. If u don't know how to find Palkia, this is how u get there:

                    You have 2 go through Celestic or Hearthome town and city. If u see a galactic grunt, that means ur @ the wrong place. That means u went through Enterna. U should use rock climb when u need 2 in the cave. @ confirm ur going the right way, you'll go through a foggy place. Then you'll get out of the cave, and there will be snow... and listen the last cave, always go the long way,  the short way is a  dead end.
