British and Vietnamese cave expedition experts discovered 22 more caves in Quang Binh Province, north-central Vietnam, the Phong Nha-Ke Bang National Park management board announced on Sunday.

These caves were assessed as magnificent as the previously-found 400 caves.

The grottos are mainly in the Phong Nha-Ke Bang National Park and Minh Hoa and Tuyen Hoa Districts.

They have a length ranging from 30 to 572 meters each.

The four longest caves include Va (516 meters), 12/2 Dry (404 meters), Vuc Hung (430 meters), and Ong Dau (572 meters).

The caves’ depth ranges between 32 and 154 meters each, while their entrance height is 46-550 meters each.

An expedition expert said each of the newly-discovered caves has its own characteristics and features geological values of areas in the Phong Nha-Ke Bang National Park.

Pham Hong Thai, director of the Phong Nha-Ke Bang National Park management board, said the board needs to do in-depth surveys and research to further clarify the values of the newly-found grottos, before working out an appropriate plan to preserve and sustainably exploit them.

Quang Binh Province has earned the title of Vietnam’s 'Kingdom of Caves,' boasting over 400 discovered caverns.

Among them, Son Doong stands as the world's largest natural cave, while En ranks as the third largest.
