The Phong Nha Ke Bang National Park is a UNESCO World Heritage Site located in the Bo Trach and Minh Hoa districts of Quang Binh province in Vietnam. The national park is home to a limestone zone of more than 2000 square kilometres and was created to protect one of the largest karst regions in the world with 300 craves and grottoes and the ecosystem of the limestone forest. The world’s largest cave was discovered in 2009 located in the national park with a depth of 150m and a length of almost 9 kilometres.

The karst in the national park was evolved since some 400 million years ago and is the oldest karst area in the whole of Asia. Massive tectonic changes results in 5 stages of Earth crust development and movement in the area. Inscriptions discovered in the late 19th century of the Champa people which was a Hindu Kingdom craved on altars in the caves shows that it was inhabited long before the area became part of Vietnam.
