>>37472964I messed up with Ula-Ula, you're right, after Po Town it should go back to the ghost trial, right? Poni Island's path is not drawn at the right entrance point to Poni Canyon, but it's just going backwards the way it came. (7) refers to a section of Poni Island that is blocked off until the end. I think there's a desert region on Ula-Ula that is also inaccessible until the end.
I've seen a lot of this complaint that Alola is a straight line, but I don't get it. It's loops and branches most of the time.
