What is main idea of the passage
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 more than two hundred metres wide, one hundred and fifty metres high,
and nearly 9 kilometres long, with caverns big enough to fit an entire street inside them. 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.
