Walkthrough: At the end of Route 10 is the Bus Stop that will take you up Mount Hokulani. Once at the top, you can descend part of the mountain to Battle both Wild Pokemon and Trainers. At the top of the Mountain is the Observatory, where your next Trial is found. However, before you can go into the building, the former Captain of the Trial, Molayne, will want to see if you are ready with a battle first.
