The headquarters of Phong Nha-Ke Bang National Park is an administrative and conservation base in Quang Tri province, Vietnam, rather than a single cave attraction. For travellers, its importance lies in understanding the protected landscape and finding official information before choosing among very different cave, forest and river experiences. Tickets and departures are handled at the relevant tourism centres and operators, not by simply arriving at an office marked “headquarters.”
UNESCO first inscribed Phong Nha-Ke Bang in 2003 and extended it in 2015. In 2025 the property became transboundary through the addition of Hin Nam No National Park in Laos. The combined World Heritage site now covers 217,447 hectares with a 295,889-hectare buffer zone. Its limestone history reaches back about 400 million years, making it one of Asia’s oldest large-scale karst landscapes. UNESCO reports more than 220 kilometres of documented caves and underground waterways, alongside exceptional forest biodiversity.
