It's not a cave? I remember it being enclosed by rock, and being small. Maybe it had clouds above, but it sure had a cave feel.
I'm not trying to be mean to OoT fans, I just think most of them say Ocarina is better because it brings back nice memories. They base it on nostalgia rather than quality, and TP doesn't get the respect it deserves. But this is all just my opinion, sorry if I sounded like an ass.
