I think it's called Muck Island. Its the one where you find all the armor and weapons laying around and has a fishing village. I've explored Prince whatever his name is Cave and cant find a way off the d** ned island and its pissing me off.

There's a hole in the North Eastern part of the cave that you have to fall in (walk next to it). You will see a skeleton on the ground. Search him and you'll find the necklace or whatever that the old lady wanted. That'll let you leave.
