A few months ago I was flying through Mulgore and found this little spot in the mountains above Red Rocks.
From the top of the plateau, you can see both a cave and some staggered painted rocks. Following these illustrations, you’ll come across a tauren camp, which as far as I know has always been abandoned, even though there’s a raging fire.
Looking past buffalo rock, you can see one path leads to a blockade but with flying or via the zeppelin, this otherwise unknown area is now easily accessible.
The cave below looks like any other cave but venturing inside you quickly find that it’s empty. Whether this area was originally designed for something other than RP, it’s still a nice spot to visit.
