Son Doong Cave has become more famous after the American Broadcasting
Company (ABC) aired a live programme featuring its magnificence on ‘Good Morning
America’ in May 2015.
Located in Quang Binh Province, Son Doong Cave was discovered by a local man named
Ho Khanh in 1991, and became known internationally in 2009 thanks to British cavers,
led by Howard Limbert. The cave was formed about 2 to 5 million years ago by river
water eroding away the limestone underneath the mountain. It contains some of the tallest
known stalagmites in the world - up to 70 metres tall. The cave is more than 200 metres
wide, 150 metres high, and nearly 9 kilometres long, with caverns big enough to fit an
entire street inside
them. Son Doong Cave is recognised as the largest cave in the world
by BCRA (British Cave Research Association) and selected as one of the most beautiful
on earth by the BBC (British Broadcasting Corporation).
In August 2013, the first tourist group explored the cave on a guided tour. Permits are
now required to access the cave and are made available on a limited basis. Only 500
permits were issued for the 2015 season, which runs from February to August. After
August, heavy rains cause river levels to rise and make the cave largely
inaccessible.
