Puerto Princesa City
Underground River


Spanning a staggering 8.2km, the Puerto Princesa Underground River is the second longest underground river in the world. When you boat along this deep, dark, and long tunnel, it’s like exploring an old mystery in the guts of the earth. Some of the chambers you’ll see are so huge, they’re as big as cathedrals.

The dripping crystalline stalactites and stalagmites, along with the sound of flying bats and the ticking of unknown animals, sometimes offer a break in the pervading silence. People who have gone deeper in the tunnel even found age-old fossilized bones protruding on the walls.

This underground river is not just a natural wonder but an archaeological treasure. This is why it’s one of the world’s New 7 Wonders of Nature and one of the most visited UNESCO World Heritage Sites in the Philippines. It’s quite a unique experience, it borders on the strange and fascinating.

The tour comes with a pre-recorded audio guide, but you can opt to unplug this from your ears and simply appreciate the river’s quiet beauty. Before entering the tunnel on a local boat you’ll also get a view of a karst limestone mountain range and the surrounding forests.
