theres a place in Hyjal i found while there just cooling out my lag and i found a opening mountain close to the entrance there it's kinda like a path but anyway at the end of the path theres a drop drink a slow fall potions thin jump at an angel so you hit the mountain not to far from where you jumped when you land there will be another drop slowfall down that the same way dont go to far or you'll end up in ashenvale but if you do it right you should see a mountain coverd in green smoke it's nothing big but it's something to know =)
