The Puerta Princesa Subterranean River National Park is remarkable. It reunites a set of caves which an underground river travels through, in the heart of a luxurious primary forest. For adventurers.

My suggestion
Do the Monkey Trail trip which leads to the mouth of the river; you don't need a guide, contrary to what the hotels try to tell you, it's very well marked out with buoys.
