This UNESCO World Heritage Site offers visitors a unique opportunity to explore one of the world's longest underground river systems while surrounded by stunning limestone karst landscapes.
Location and How to Get There
Situated in the northern coast of Puerto Prinsesa, Palawan, this remarkable attraction is easily accessible from the city center. Visitors can reach the park by taking a van or bus from Puerto Prinsesa市区 to Barangay Cabayugan, followed by a boat ride through the pristine coastal waters. The journey itself is part of the adventure, offering glimpses of the area's rich biodiversity and crystal-clear waters.
Unique Features and Attractions
The underground river system extends approximately 8.2 kilometers and features an impressive cave chamber that ranks among the world's largest. The river flows directly into the South China Sea, creating a fascinating saltwater ecosystem within the cave system. Visitors can marvel at spectacular stalactites and stalagmites that have formed over millions of years, illuminated by professional lighting systems that enhance their natural beauty without causing damage.
