One of the reasons I love to hike is because it seems that I always find some unique natural feature that amazes me. Could you imagine finding a cave over 6 Km long and in some places200 m high?
Cavers find an exit in 6.5 km long cave in the Jungles of Vietnam.
This world’s largest cave was first discovered in 1991 when a Vietnamese Jungle man named Ho Khanh. No one had entered it prior because the loud noise from the wind and under ground river freaked everyone out.
In mid April 2009, after hiking for six hours, negotiating a deep chamber and 2 underground rivers, a British – Vietnamese expedition reached the chamber of the amazing hang Son Doong cave.
