Puerto Princesa Underground River

When streams of waters create waterways, rivers are formed. But it is a wonder of nature when the water passes through a cave and drains itself to the sea.

The Puerto Princesa Underground River is a subterranean waterway under a mountain range. It is one of the longest rivers flowing under the earth.

What makes it more beautiful is the system of navigable caves which boast of karst formation and internal natural stalagmite, stalactite, and columns.

The river is a part of the larger Puerto Princesa Underground River Natural Park, which is included in the list of UNESCO World Heritage Sites.

Also, it won a spot in the global poll for the Seven Wonders of Nature. It is included in the list because of the uniqueness of its formation and because of its rich mountain-to-sea ecosystem.

The coastal part (St. Paul Bay) features mangroves, grassy sea bed, and coral reefs.

What is the the Puerto Princesa Underground RIver?

Underground River is a unique formation of nature. The PPUR is the longest navigable subterranean river, and second longest of its kind (the longest is in Mexico).

It is named Puerto Princesa Underground River after the city of Puerto Princesa, which has its jurisdiction. The river (locally known as the Cabayugan River) passes through the mountain range called St. Paul Mountain Ranges. The journey of the water is composed of 8.2 kilometers from river tributaries into the West Philippine Sea (earlier name: South China Sea).

Where can we find the Chocolate Hills?

PPUR is in the northwest of Puerto Princesa City, the capital of Palawan. Palawan is an archipelago-province in the western Philippines.

How did mother nature mold this wonder?

The Cabayugan River and its tributaries formed their waterways through the cavities of the mountains in the St. Paul Mountain Range. The river is sloped about a hundred meter and rapidly made ways to pass into the systems of caves. It found its way to the St. Paul Bay which is directly a part of the West Philippine Sea.
