The Tunnel in the Cliffs map in Kingdom Come: Deliverance 2 isn't your typical treasure hunt. Usually, you'll find a parchment map that you can carry around and solve at your leisure, but here, the map is etched into a cave wall so you can't exactly take it with you—besides grabbing a screenshot, that is.
You'll find this map at the Tunnel in the Cliffs location in southern Apollonia, where a bunch of bandits seem to have fought and killed each other. In the tunnel itself, you'll spot a skeleton with a dagger whose dying act seems to have been carving a map into the cave wall. It's a little hard to spot, but if you follow its directions you can locate some loot.
