First you need to see the lake pokemon captured by team galactic,you do that by going to the 3 lakes of sinnoh.Then going into team galactic headquarters and beating the head,cyrus and freeing the lake pokemon in the back room.Then you go to Mt.Coronet from oreburgh because it is faster.Go up to the spear pillar and fight some more team galactic people and fighting the boss again.Then you fight the legendary pokemon according to your game(palkia for pokemon pearl,dialga for pokemon diamond).Finally,go to the grand lake hotel east of pastoria city.The person blocking your way is gone and you can go to sunyshore city.
