The Underground River in Palawan, officially known as Puerto Princesa Subterranean River National Park, is a spectacular natural wonder and UNESCO World Heritage Site that captivates visitors with its stunning limestone karst formations, unique ecosystem, and extraordinary cave experience. It is renowned as one of the New 7 Wonders of Nature, making it a must-visit destination for travelers exploring the Philippines.
Features of the Underground River in Palawan
The river itself is the longest navigable underground river in the world, extending over 8 kilometers beneath dramatic limestone mountains before emptying directly into the sea. Visitors can embark on a guided paddle boat tour inside the cave, traveling approximately 1.5 kilometers for about 45 minutes. Along the way, you’ll encounter breathtaking natural rock formations like stalactites and stalagmites shaped over thousands of years, as well as fascinating wildlife including several species of bats that roost within the cave.
The cave’s interior offers a surreal, almost cathedral-like ambiance, highlighted by formations dubbed the “Virgin Mary,” “Ship,” and “Cathedral” due to their shapes and grandeur. The water in the cave is saline, influenced by tidal movements, adding to the uniqueness of the ecosystem. Surrounding the cave is a lush tropical forest that is home to diverse flora and fauna, contributing to the park’s ecological importance.
