Phong Nha cave is a spectacular natural wonder located in the heart of the Phong Nha-Ke Bang National Park, in the Quang Binh province of Vietnam. The cave is one of the largest in the world, and is home to some of the most impressive stalactites and stalagmites in the country. A system of underground rivers and lakes make up the cave, and visitors can explore some of the more than 7 km of passages on offer. The Phong Nha cave is a major tourist attraction in Vietnam, and is well worth a visit for anyone travelling in the area.
