In addition to mountainous regions and beaches, Vietnam is full of beautiful caves. It becomes obvious to spend a few days at Phong Nha - Ke Bang Park to discover these amazing underground cavities, extraordinary rock formations, stalactites and stalagmites of all sizes...
The region is distinguished by its network of caves and caverns among the largest and most complex in the world. It is estimated that the park is home to more than 300 caves, caves and sinkholes of which only twenty have been explored. In 2009, a team of British speleologists discovered the largest underground network in the world, with a total length of more than 130 km traveled by the longest underground river in the world.
To visit this cave, the only choice is to take the boat (despite the price, there is little choice since the cave of Phong Nha is immersed and it is accessible only by a boat). Regarding the price, you have to pay for the rental of the boat (360.000d / boat / 12 people maximum, you can rent this boat), the ticket of the visit of the cave of Phong Nha (150.000d / pax), the cave of Tien Son (80.000d / pax) ....
In case you can not visit the submerged caves, the cave of Thien Duong (nicknamed "cave of paradise") is an ideal choice. From Son Trach (which is 44km from Dong Hoi, capital of Quang Binh province), you take the motorcycle road to the south-east to reach the cave of "paradise". Once inside the cave, you have the impression of being immersed in the heart of an alien, lunar and fantastic scenery
