I have been trying to reach this feather, but I cant seem to find a tree or a path up the mountainside to get there. The feather looks to be fairly close to the cave with the cave drawings. Any help would be appreciated.
This is for the feather in the top right of Black Creek. The easiest way to the tunnel entrance is to go to the village with the interactive people. from there just head straight to the marker exiting out the back of the village (the back being closer to the water)
If you keep straight you should run straight into a cave.
