Known as the most incredible cave, Son Doong Cave in Vietnam which is so big that it harbours underground jungle and a river has been opened to public now. The cave was discovered in 2009 but was not open for public or tourist.

Discovered was made by British cavers, led by Howard Limbert. The cave will finally open to tourists and will enter its first batch of 220 adventure travelers by the end of August 2014.

The cave is so large that it could easily fit in a skyscraper inside it. Located in the Phong Nha Ke Bang National Park in Quang Binh province near the Laos-Vietnam border this cave will be a prominent tourist destination from 2014.

Oxalis, a Vietnam-tour company has opened bookings for six days and seven night tour package for the world’s largest cave’s exploration. Oxalis is the only official operator with permission to host tours to Son Doong Cave.

The cave was restricted to tourists but with recent approvals from the Government of Quang Binh Province has allowed pilot tours in to Hang Son Doong from present till end of August 2014. Two of the very best caving experts from the UK will accompany each tour of Son Doong Cave.

With 30 m tall trees and rivers flowing inside Son Doong literally means mountain, river and cave. These distinct features set it apart from other caves located at different parts of the world.

The cave was formed two to five million years ago by river water eroding away the weak limestone underneath the mountain creating huge skylights. Fossils as old as 300 million years have also been found inside the cave. So if you’re interested just pack your bags to take a firsthand look of this incredible wonder of nature.
