Having a ton of trouble with this puzzle... I've got 3 possible leads, and none of them seem to be working.
I have tried: Mimicking the path shown in the northern cave, Mimicking the path leading to the obelisk in the southeast, and navigating using the number grid in the hidden cave above the shack.

What items have you found in that zone, Pixel3r? It sounds like you might have missed 1 or 2.
There are also 2 areas in that zone that could be described as a maze, and it sounds like you're referring to the northwest coral forest one. So OSOGR's first thought was more correct, but you might be missing a couple steps before you have everything you'll want for it.
I kinda get where you're coming from but that runs counter to the philosophy of the game.
