She is in sunyshore ( or something ) city just standing at the beach to make sure you wont go surfing behind her after you defeated the 8th gym leader and earned waterfall.
On your way to the spear pillar one of the rooms you have to go through has a big pond use surf and at the farest north is a waterfall.
Dratini can be found by using the Super Rod in the area behind the Waterfall in Mt Coronet.
