It is actually in route 131... and is at the sea where a few rocks will be there and there is a small narrow path between the rocks where it leads to to sky pillar.
you find rayquaza in the sky tower, you surf down route 28. hope this helps a lot! :)
Its before Pacifidlog Town, before you reach the town, keep surfing closer to the top, there'll be a gap soon that shapes like a U bend, enter the bend and the Sky Tower will be further above. Use the PokeNav if you are still uncertain
Sky Pillar is located toward the northern edge of Route 131. As you surf across the water, just find a path that leads upwards to Sky Pillar.
just swim around route 131 then go to sky tower. You can't miss it!!! HOPE I HELP!!!!!!
