After visiting the cave, many people recognised its irresistible magic, saying that this is really the most beautiful wonder of the Creator on earth.

Thien Duong was labelled the world’s most beautiful and magnificent cave when it was discovered by scientists from the British Cave Research Association in 2005.

Located about 4 km west of the Ho Chi Minh Road, the cave, which is believed to be formed hundreds of millions of years ago, is surrounded by underground streams and rocky mountains.

Thien Duong Cave is 30-100 metres wide, with the widest point measuring 150 metres. With a length of over 36 km, it is considered the longest dry cave in Asia.

Besides Son Doong and Thien Duong, other well-known caves include En and Pygmy, which are said to be the third and fourth biggest in the world.

Quang Binh province recently discovered 58 more caves, all of them located in Minh Hoa district.

According to the provincial Department of Tourism, Quang Binh welcomed 3.3 million visitors in 2017, up 70.9 percent against the same period last year, including 130,000 international tourists, up 156 percent. The tourism sector grossed over 3.7 trillion VND (161.8 million USD) in revenue.

Over 1.8 million tourists came to the province in the first half of this year, up nearly 17 percent year-on-year. Foreign arrivals surged by more than 22 percent with nearly 90,000 visits.

In 2018, Quang Binh strived to greet 3.5 million tourists, including 120,000 foreigners.-VNA
