The caves have a total length of 11.7km. Of the new discovers, 20 were found in Lam Hoa commune of Tuyen Hoa district, as well as inHoa Phu and Hoa Son communes of Minh Hoa district, while the rest are inside PhongNha-Ke Bang National Park.
The search for the new caves involvedexplorers from the UK, Australia, and New Zealand who had worked for threeweeks with support of tour guides and a number of locals.
Howard Limbert, theleader of the team, said that the newly cavesare mostly wet, and although they are small, they are quite intriguing comparedto many others found in Quang Binh. He further added that unlike Son Doong, En,and many other caves which have only one main entrance, this new cave systemhas multiple entrances and exits. Some of the new are even interconnected,creating multiple cross paths that make exploring inside extremely captivating.
In order to exploit the caves for tourismand exploration activities, the BCRA recommends that Quang Binh conduct furtherresearches to evaluate their safety, ceiling heights, flow, and geomorphology ofthe caves.
With about 500 caves discovered, Quang Binh is renownedas the country's kingdom of caves. There are over 40 caves in the localitywhich are open to tourists. Son Doong is the world's largest, while En and Pigmy come in at second and fourth./.
