Note: I'm not talking about the location that allows you to spend Nopon coins in the Dannagh dessert. There's a seemingly large area of cliff in the middle of Colony 4, Ribbi Flats and Dannagh Dessert that looks like it should be accessible, but I can't find any way up to it. There are containers and husks there too.
Is there a way up? Please don't provide any major spoilers beyond chapter 3 - if access is locked to a certain chapter, quest or traversal skill then that's fine to say so.
