World Heritage Site “Puerto Princesa Underground River National Park” The last unexplored region in the Philippines!

Palawan Island is a long, narrow island located in the southwestern Philippines. The fifth-largest island in the Philippines, Palawan is south of Luzon Island, where Manila is located. In the middle of Palawan Island lies the city of Puerto Princesa, a treasure trove of nature surrounded by a blue sea.

The Puerto Princesa Subterranean River National Park, a World Heritage Site, is located in the northwestern part of Puerto Princesa. Within the St. Paul mountain range, a navigable underground river over 8km long flows through a cave and out to the sea. Let's go on an expedition to Puerto Princesa Subterranean River National Park, also known as the "last frontier of the Philippines", a world-renowned rarity.

About Puerto Princesa Subterranean River National Park

The Puerto Princesa Subterranean River is approximately 120 meters wide, about 60 meters high, and over 8 kilometers long. It is believed that the huge limestone cave through which this underground river flows was formed when a large amount of rainwater eroded the limestone, creating an underground river that flowed into the sea.

The lower reaches of the Puerto Princesa Subterranean River are connected to the sea, and the influence of the tides has created a rare ecosystem unique to this place. In recognition of its biodiversity conservation and outstanding natural beauty, Puerto Princesa Subterranean River National Park was registered as a World Natural Heritage Site in 1999.

Access to Puerto Princesa Subterranean River National Park

Several airlines offer daily flights from Ninoy Aquino International Airport in Manila to Puerto Princesa International Airport that take about 70 to 90 minutes.

From the airport, you can take a van or a bus to Sabang, the jump-off point to the Underground River. The travel time is about 1.5 to 2 hours. You can also hire a private car or taxi if you prefer a more comfortable and convenient option. Once you arrive in Sabang, you need to register at the tourism office and get a permit to enter the Underground River, then you will take a short boat ride to the mouth of the cave.
