This area is completely lighted, has a road within it, and had NPCs walking around. The few you can talk to behave like IF guards telling you how to get to a few places but always leading to IF.
The only way we have found to get to this area is to go to the Ironforge Airport first and then very carefully go down the mountain. Standing at the airports griffon master start heading down the mountain and head a little left (west). Just follow the paths you feel is safest to go down. You will soon see the buildings of the farm.
