Where is the pp max in poni canyon?

Question

I've been trying to search for a video tutorial for an hour now and the only thing that google shows is a way to farm up pp ups or just a walkthrough of the entire canyon. So can anyone put a video or image in which area is the pp max in? I know it's hidden but I have no idea which area

Answer 1

Canyon, after the third cave, on the cliffs, between the rock and the wall at the end of the third bridge (hidden)
