Possibly the world's largest cave passage, Hang Son Doong was discovered in the heart of the Vietnamese jungle by a British caving team. At 150m long and 200m high, it is seven times as high as York Cathedral.'It is a truly amazing sized cave and one of the most significant discoveries by a British caving team,' said Adam Spillane, a member of the 13-man expedition team.
The cave was originally discovered in 1991 by a Vietnamese Jungle man called Ho Khanh.The cave had not been entered since, due to the terrifying wind and noise from the large underground river.
The team spent five days exploring the cave after trekking six hours through the jungle to find it. They had to negotiate two underground rivers before reaching the main passage.
