Well normally you can only find zubat in there but the reason why its called altering cave is that you can change what you find in there by using an E reader machine and E reader cards.
A special Mystery Gift could be used to make it possible to encounter shuckle in the Altering Cave, but that Mystery Gift was never distributed.
Altering cave is on 5 or 6 island.

You can't do anything with altering cave unless you have an E Reader.
To get to the altering cave you must first beat the Elite Four and the champion once. Then go to route 103. The cave door is there. WARNING: There are only zubats there, but you can find shiny zubats so, I guess it is a trade off!
There are no moveable rocks in Altering Cave.
Altering cave does not change into traveler's cave. Altering cave can only offer new Pokemon (since all it offers are zubat) after using Mystery Gift.
