Phong Nha National Park



Phong Nha National Park (Vietnamese: Vườn Quốc Gia Phong Nha) is a national park in Quảng Bình Province, Vietnam on the border with Laos. It is the location of Hang Sơn Đoòng, the largest cave in the world.

The park's terrain has a heavily rugged limestone karst landscape, similar to Hạ Long Bay or Cockpit Country in Jamaica. The park is a part of the Annamite Mountains, and the terrain continues past the border with Laos, which forms a straight stretch through the park, due to the rough terrain being difficult to survey.

Access
The most popular route of access is from Đồng Hới, which has a railway station and an airport. The park is also accessible by road, and has numerous scenic and winding roads that traverse the park.

Inhabitants
The park is home to numerous small minority villages inhabited by the Bru people, Chứt people, or other small tribes. Some villages lie deep within the jungle and are only accessible by a long walk.
