The HM Waterfall, which is given to you by Jasmine in Sunyshore city
you have to have the move: waterfall. im pretty sure you get it from someone and beat a gym leader to be able to activate it.
It depends, what waterfall exactly (which location?) ? They just will show you new areas once you get past them. Also, special ones: a waterfall precedes Victory Road, another one precedes the Pokemon League. :)
you have to get the HM waterfall to go over the waterfall
u have to get waterfall from a girl on sunnyshore beach.
you have to win the battle at the sunnyshore gym then go down where jasmin is and talk to her and she will give you the hm waterfall.
you are unable to send any items from the past games to pokemon black/ white
what?
Victory Road is the path that leads to the Elite 4 in Pokemon Diamond version. To get past it, you need to have all the badges.
You blow on the dsi, i'm not sure if a ds can recognize wind on pokemon diamond or not.
you have to find hm07 called waterfall you get a water Pokemon and use hm then u could climb waterfalls.
you need to get waterfall which can be found on the ice path from mahogany town to blackthorn city. :D aydelie 101
Go to sunyshore city, then go up in the water (make sure you got surf and waterfall) to swim and to go up the waterfall to The Pokemon League then you will reach a Pokemon league cave past it and then go to the Pokemon league heal your Pokemon and fight
