I wuz flyin around with the highwind when i found this island with a hole like a cave but nowhere to land... WHAT IS UP WITH THAT?

If u know anything can u please tell me?:D

Oh, I believe that is then Island were you get Knights of the Round summon. You need a gold chocobo to get to it.

Its Also Possibly Cactaur Island... Either Are Useful

The unmapped island with the cave is where you go to get Knights of the Round - but like Ark Mune said, you need to have a gold chocobo to get there.

Which is just a bitch :(

lol if u fly around a lot then you should notice a lot of unreachable places. like where you find vincents wife. or where you get mime materia. or cactor island even. i can't remember too well but cactor island is under the grand canyon and the only inhabitants are cactors. these things tend to run instead of fight. but if u morph them you get a good item.
