i found, while flying between iornforge and wetlands, an area with a long run way and gyrocoptors with a gryffin flight path and for hours ive been trying to find my way up with no luck. Is there any way up there???

To the immmediate left of the exit from Dun morugh to Loch modan you will see a tree, behind it is a small crevace.

You need to jump up that crevace into the mountains and explore around a little bit. It takes a little while to do so don't give up.

But there really isn't anything there it's a WIP

I would show you pictures of what it looks like up there but i dont really know how.  so i will tell you.  There are buildings up there, however they arent able to be entered, or are fake and you can walk right through them.  Also, there is a Gyrocopter track and about 6 or 7 Gyrocopters.  There is an area, on the lake, where it is a never ending battle between the Ironforge gaurds there, and trolls that keep popping out of this cave.  I ventured to the edge, and on the edge they have an alliance flight path person, with 2 griffons, however the flight path person does not speak.  Basically the whole thing is under construction. 

Hopefully it will be up and running soon though.

I have another question about another place.  If you are flying from Moonglade to Darnassus, you will fly over the mountains in between Moonglade, and Darkshore and you will notice what looks to be a troll village there.  Does anyone know how to get there?

I found out how to get there. Its pretty neat but you can definitely tell its not finished, possibly content for patch or exp pack. If you would like me to show you i have a character on Kul Tiras and Garithos. Lamb on kul tiras, jth on garithos. Both alliance. send me a tell in game if you want to go.

I also found a hidden farm in wetlands. Cant get to it by normal means, have to find a path through the mountains. Again though, a work in progress as well. If you want to go to either place just let me know in game.

Currently i have been running around looking for other unfinished areas, mostly boring but occasionally you come across a really cool place that people have never been to.

I dont think the places are under construction, i think that they are just for sceneray, besides, in patch 10, blizzard said that they changed the terrain slightly so u cant go to IF airport anymore... though i never found that troll village
