Gua Ikan

The best known of the four caves sitting together just outside Dabong town, and the easiest to walk into. The rock is Gua Musang Formation limestone, laid down somewhere between the Middle Permian and Late Triassic, which puts it a couple of hundred million years back. Inside there are chambers, stalactites, an underground river, and coral fossils in the walls from when all of this was seabed.
