Ok - found this whilst waiting for more people in a raid to Kara.
Easy to get to, and very cool.
This guide shows you how to get to the spot shown below in SW
Step 1: Come out of the AH and stand a few foot away from the door.
Step 2: Look to your right. You will see a lamppost similar to the one below.
Step 3: Walk up to it from that AH side.
Step 4: Stand in the middle of the box closest to it. (AH side)

Step 5: Jump and tap the 'w' key. Experienced walljumpers will find this easy.
Step 6: You should be standing on a invisible platform whilst jump up. Jump about twice, and then jump onto the top of the lamppost.
Step 7: Type /dance for free gold.
