Phong Nha- Ke Bang national park, located to the north of the majestic Truong Son range in central Quang Binh province, is one of the world’s two largest limestone regions. The over 200,000 km of parkland includes beautiful limestone formations, grottoes and caves, and evocation names such as Lion, Fairy Caves, Royal Court and Buddha.
Besides the grotto and cave systems, Phong Nha-Ke Bang has the longest underground rivers, the largest caverns and passageways, the widest and prettiest and banks, and the most astonishing rock formations in the world. In addition, Phong Nha-Ke Bang is home to archeological and historical relics such as an ancient hieroglyphic script of the Cham ethnic minority, Xuan Son ferry station, Ho Chi Minh Trail and Road 20 used during the US resistance war.
In 2000, Phong Nha-Ke Bang National Park was designated a Unesco World Heritage site.
Phong Nha means Cave of Teeth and was used by the Northern Vietnamese as a hospital and ammunition depot during the American war. In 1990, British scientists surveyed 35km of the cave and discovered the main cavern is nearly 8km long with 14 other caves nearby.
Boat is the only transportation means to explore Phong Nha Cave. Once you get further into the cave, it is mostly unspoiled.
The cave system is electrically lit but you can bring a torch for better exploration.
When to Visit
The best time to visit Phong Nha Caves is the dry season, between February and April when the weather is cool and there is no flooding.
Travelers should check carefully the weather in this area during November and December before travel as during this period, the river is prone to flooding; the underground cave may be close. Though it's possible, but also may be dangerous to visit the dry cave.
