The Capisaan cave system (Class 1 and 2) in Nueva Vizcaya is the fourth longest cave, surveyed at 4.2 km. It is a geologist’s paradise because of the beauty of its cave formation.

The Puerto Princesa Subterranean River National Park (Class 2) in Palawan, a World Heritage and Ramsar Site, features a 20-million year old Sirenia fossil in its wall and an 8.2 km navigable underground river that empties into Honda Bay.

Despite the country’s cave biodiversity and significance, most of these are in danger due to increased demand for recreational sites, vandalism, treasure hunting, mining, pollution, illegal collection of cave resources, and rapid urbanization
