Son Doong is the name of the world's largest cave in the world. It is not only huge, but also a very beautiful place filled with wonders. It is almost like an alien world on Earth. What is truly fascinating is the jungle inside the cave. As you can see on these breathtaking images this is without doubt one of the most remarkable places on our planet.

Son Doong cave is more than 200 meters wide, 150 meters high, and approx 9 kilometers long, with caverns big enough to fit an entire city street inside them. It located in Son Trach, Bo Trach District, Quang Binh province, Vietnam. The cave was found by a local man named Ho Khanh in 1991 and was recently discovered in 2009 by British cavers, led by Howard Limbert.

It was created 2-5 million years ago by river water eroding away the limestone underneath the mountain Where the limestone was weak, the ceiling collapsed creating huge skylights. The underground caverns are not easy to access. Son Doong is situated below another cave in Phong Nha-Ke Bang, though its entry passage is very difficult to traverse. It takes explorers 6 hours of walking through a 10 kilometer long forest path from Truong Son Highway to reach the mouth of Son Dong cave. The Son Doong cave is so large that explorers are still searching for its end!
