This area is quite tricky.
The starting room, or the one just north of it, has side paths, one east and one west, each of which will eventually sort of loop back around toward the center of the map. Each path has a mini-boss near the end of it, so you'll know when you're done. You have to hit a couple of switches in order to light up the crystals, which will unlock the door to the cave.
Heh, just running straight north and into the cave would be way too easy. The Forest of Winds is the third big dungeon and, in my opinion, probably the second hardest to navigate. It's been awhile since I did this one, but yeah...look out for side paths and remember that you have to loop around (for instance, go east awhile, then north, then eventually west again).
Hope this helps a little.
