Quang Binh in central Vietnam, renowned for beautiful beaches and breathtaking natural landscapes, has become one of the most popular destinations for both domestic and foreign travellers in recent years.

Last year, Dong Hoi city of the province welcomed nearly 1.1 million visitors, up 29 percent year-on-year. The city is home to a number of historical and cultural relic sites, including Dong Hoi Citadel and Church of Tam Toa.

The province is also blessed with Phong Nha – Ke Bang National Park, a paradise for cave explorers which was twice recognised as world natural heritage sites by UNESCO in 2003 and 2015.

It was listed among the “Top experiences in Vietnam” in 2017 by Lonely Planet – a renowned travel publication.

Located in the heart of Phong Nha – Ke Bang Nation Park is Son Doong cave, the largest of its kind in the world recognised by three international organisations, namely Guinness (based in the UK), the Association World Record (based in Hong Kong) and WorldKings (based in the US and India).

Son Doong was discovered by a local in 1991. It was first explored in 2009 by the British Cave Research Association and has been open to the public since 2013.

The 1,645m-long cave system, which extends through a mountain, was named one of the most captivating caves on earth by National Geographic.

Geologists say the cave formed two to five million years ago. It is roughly 6,5km long, 200m high and 150m wide, exceeding the former world record of Deer Cave in Gunung Muli National Park in Malaysia.-VNA
