Here is a way to get to secret area i discovered while leveling so i made video to share.
Found it in Skull Splitter Valley, lets you go anywhere in the mountains of Dun'Morogh, Badlands, or Lochmodan, I have used this to reach Ironforge Airport, a cave in mountains i saw from FP in Dun'Morogh and exploration in mountains all around.
