Vietnam promotes ‘super’ cave


HANOI, 6 July 2018: An online knowledge contest on Phong Nha – Ke Bang National Park in Vietnam offers the grand-prize winner a US$6,000 tour of Son Doong, the world largest cave.

The contest is held as part of activities to celebrate the 15th anniversary of the park’s recognition as a UNESCO World Natural Heritage.

A total of 128 prizes will be granted to outstanding entrants, according to the Vietnam National Administration of Tourism.

The objective is to promote the national park to visitors, to boost tourism development in Quang Binh Province.

Details of the contest were released during a media briefing in Dong Hoi City, Quang Binh Province, last week.

Open to Vietnamese citizens and foreigners, aged from 14 to 70, winners will be announced on the website and notified via registered mail after the contest concludes 31 December, 2018.

To register, contestants must visit to fill in their personal information as well as respond to questions. The webpage has Vietnamese, English and French versions.

Located near the Laos–Vietnam border, Son Doong has a fast-flowing subterranean river and is recognised for having the largest cave cross-section, worldwide, believed to be twice of Deer Cave in Malaysia, the next largest known cave passage in the world by volume.

The cave runs for approximately 9 km and is punctuated by two large ‘dolines,’ or funnel shaped sinkholes, where the ceiling of the cave collapsed. The dolines allow sunlight to enter sections of the cave, which has resulted in the growth of trees as well as other vegetation.
