You must defeat Team Aqua in their Lilycove City base (right next to the Wailmers). To gain entrance to the base, you must first go to Mt. Pyre and climb to the summit.
First go to the Pacifidlog town (Where Wailmers are at high LEVEL), Next, use a super rod to catch a LvL 34,35,36 or if lucky a LvL 36 Wailmer, Then feed it few rare candies or train it to level 40 and it will evolve into a Wailord.
