In Durotar bottom left of the area there are a bunch of islands.

1. go as far out as you possible can go staying out of the fatigue zone.
2. look east and you will see a couple islands
3. run you might want to use swim speed pots
4. get to the shallow water there
5. run to the other side
6. you will see a little untextured pathway run down it, its pretty cool.

Been there and my warning is after you get towards Dustwallow marsh the strip turns inland and you can fall off if you jump........it sucked and I had to have a GM rescue me
