Phong Nha-Ke Bang has a spectacular limestone karst topography and extensive cave systems, which make it one of the most outstanding geological sites in the country. The centrepiece of the site is the Phong Nha cave, through which an underground river flows. The mouth of this cave is 30 m wide and 18 m high, and it is possible to enter up to 1.5 km into the cave. In addition to the Phong Nha cave, 16 other caves have been surveyed to date at the site, with a total length of over 60 km.
The Phong Nha cave system is an increasingly popular tourist destination, with recent investment in facilities and upgrade of access. Large numbers of tourists visit the caves daily, stretching the carrying capacity.
