just get a chocobo from the imperial then exit there and turn left.Once you get in there then you should find it pretty easy.Also if your going into the Henne mines then make sure your about level 28-30.The fiends in there are pretty tough and my cousin said the boss in there was tough to.I'm headed into the mines and i'm leveling up my people to level 30.Well I'm trying any way.Hope this helps.
