Son Doong Cave is in the heart of the Phong Nha Ke Bang National Park in Quang Binh province. This incredible cave was only explored in 2009/2010 by the British Cave Research Association. Situated in the deep jungle, the entrance to the cave was found by a local jungle man Mr Ho Khanh. Son Doong Cave is now the largest cave in the world and has understandably been the attention of many film companies such as the BBC (films, 2009), National Geographic (one film and many big shots, 2009, 2010, 2011, 2012), Japanese (NHK film, 2012), HongKong (film, great shots, Spring 2013) and Brazilian, Singapore, New Zealand teams currently. Son Doong cave is unlike any other caves on the planet. Inside this giant cave are two huge daylight windows which allows the light to enter many parts of the cave. At the base of these windows are large jungles which use the available light and so trees up to 30m tall are present. But Son Doong is not only about its immense size, the cave has amazing examples of some of the best speleothems in the world. Giant stalagmites up to 80m high and enormous rimstone pools are present throughout the cave. There are also excellent examples of giant cave pearls and a newly discovered side passage is full of large fossils over 300 million years old. As well as rare species of plants in the cave a number of new species of animals have recently been discovered. Monkeys, hornbills and flying foxes have all been seen in the jungle section of the caves.
