In Bahile, Puerto Princesa lays the world heritage site called Subterranean River. With a length of 8.2 kilometers, this natural wonder amazed millions of tourists because of its passable underground river. In fact, Subterranean River stands to be the worlds longest underground river along with a fascinating cave winding throughout its length and empties in South China Sea.
Where the river flows, there is a deep cave lined with marble cliffs and rugged limestone ready to excite your sights. In its recesses deeply hallowed into the winding tunnel, tourists can enjoy the sights through a paddleboat exploring rock formations, amphitheaters, and stalactite pillars.
