Way to unlock: Find a map on the corpse near the campsite.
Quest giver: - (M3,10)
Right next to the campsite, to the South of the Hinterland village, on a hill, there is a tree and a corpse on the tree. At the foot of the tree, there is a map to the waterfall, which shows the hidden passage behind one of the waterfalls. This particular one is at the beginning of the river flowing from the South to the North (M3,10a). There also is a Templar camp there (M3,11b), which is why you need to get there well-prepared.
After you clear the camp, walk over the ledge towards the waterfall. You will find a stash there, which you first need to scan, to pick it up. Inside, there is a valuable crafting item.
Rewards for completing the quest:
