Puerto Princesa Underground River is one of the longest underground rivers in the world with a length of 8.2km and is among the few that spill into the sea. The river, which hosts the ecosystem from the mountain to the sea, also holds the largest underground estuary in the world.

The Philippine island of Palawan is the site of this ecosystem with a total cave system of 24 kilometers in length. One of the most remarkable cave systems in the world, the Puerto Princesa Subterranean River National Park is featuring spectacular limestone karst landscapes.

The Puerto Princesa Subterranean River National Park, one of the New Seven Wonders of Nature re-listed in 2012, attracts travelers and explorers from all over the world with its ecological diversity and visual splendor.

The Puerto Princesa Subterranean River National Park, home to more than 800 plant species, serves as the last castle where many endangered animals can be found. Some species, including Philippine cockatoo, Hawksbill turtle, Green sea turtle ve Nordmann’s Greenshank, are trying to survive in this exceptional park.

The Puerto Princesa Subterranean River National Park has taken its national park status in 1971. And with the Ramsar Convention signed in 2012, it was fully protected. Google celebrates the signing of the Ramsar Convention that protects the Puerto Princesa Subterranean River National Park, with a special Doodle designed by artist David Lu.
