A wonderful and very cheap place! We were just us, me and my husband. They gave us the guidance who spent two hours with us telling about the cave and all this for only $ 10 for a person.
They also keep 200 iguanas (I never thought that they are so big and beautiful).
The only one problem is that you can't take photos inside the cave, but it is clear, the flash ruined the old graffiti on the walls.
Recommend to everyone!
