Located in North-Central Vietnam and surrounded by Ha Tinh Province on the north, East Sea on the east, Laos on the west and Quang Tri Province on the south, Quang Binh Province has long been well known for its spectacular landscape of mountain and sea.
From blue water and yellow sand beaches glittering under the shadows of green willow trees, mineral hot springs to plenty of magnificent caves and primitive forests in Phong Nha – Ke Bang reserve, all of them create unspoiled picturesque beauty. One of the most popular attractions in Quang Binh is Phong Nha- Ke Bang National Park, recognized as the World Natural Heritage Site by UNESCO in 2003.
With an area of 85,754 ha, the property is home to terrestrial and aquatic habitats, primary and secondary forest, sites of natural regeneration, tropical dense forests and savanna and plenty of stunning and scientifically significant caves. The 2-5 million years old Son Doong cave was found in rugged Phong Nha-Ke Bang National Park near the border with Laos, the cave is part of a system of 150 or so naturally gifted caves, many of them are still not surveyed, in the Annamite Mountains.
For centuries, river water has been eroding away the limestone underneath the mountain, creating the breathtaking Son Doong. Especially, where the limestone was weak, the ceiling collapsed creating huge skylights. Besides, Phong Nha cave's charm lies in fascinating rock formations, enchanting visitors with evocative names such as Lion, Fairy Caves, Royal Court and Buddha. Phong Nha cave has the longest underground rivers, the largest caverns and passageways, the widest and prettiest sand banks, and the most astounding rock formations in the world.
