This one is the easiest. Just find where the Mother Nanov is at the end of the Atlai river and look to your left/west (while facing/looking at Mother Nanov). Simply climb the rock/mountain formation to get the accolade.

It's also possible to get the accolade by approaching from the staging area and making your way down the mountain toward the end of the river and Mother Nanov.

Hope that helps with that particular accolade.
