okay so me and a guildie decided to go to elwynn falls yesterday, but we figured out that none of the guides really covered in and was n00bfriendly, so i made my own:
first off you must go to burning steppes.
this is where the area is on the map
go up in this "corridor" and turn to the right when u are up in the little circle formed by the mountains.
when you are up this is where you should go to jump and get outside the mountains of burning steppes. (blue line is where to go, red line is where to jump to). can be a bit tricky to get up
this is how it should look from your point ov view.
when you get up follow the blue line(on the picture)
follow it again as shown on the picture
now when u are on the top, u have two options, the first one is to go to the elwynn falls by simply going straight ahead going towards the falls. The second option is to go to the right to where the dwards that you fly over is, it is possible to get to the waterfalls if you go to the right tho, so i would recommend that.
hope that clearifies it a bit more.
