Sunnyshore City. Have fun looking for it.
You can get the HM waterfall in Pokemon Diamond and Pearl by beating the 8th gym leader and talking to Jasmin by the little beach. She will give it to you.
from jasmine in sunyshore beach if you defeated the eighth gym already.
Jasmine will give HM Waterfall to you at the beach after defeating Volkner.
you do need hm waterfall for mt. conet.There's a waterfall in mt.conet
from that gym leader on the beach of sunyshore city (must have beaten the 8th gym)
After defeating Volkner at Sunnyshore Gym, go to the beach and talk to Jasmine. She will give you Waterfall.
U don't go through the waterfall, u go over the waterfall. The goal is to have the HM waterfall. This HM allows ur Pokemon to climb the waterfall.
That HM is called Waterfall.
First u have 2 beat the gym leader, volkner. Then u go to that little beach north of the city and talk to jasmine and she will give u the hm for waterfall.
once you beat the last gym leader go out onto the beach at Sunnyshore City and a lady will give it to you.
if you have diamond that city under the Pokemon league if you go to the girl at the beach corner place thing and talk to her she will give you waterfall and you don't need diagla this is just diamond for all i know
no just like all HM's u need to obtain them you get waterfall the same way as diamond+pearl talk to jasmin on the beach at sunnyshore city.
