The British Caving Association has found 22 new caves in Quang Binh Province, north-central Vietnam, the management board of Phong Nha-Ke Bang National Park in the province announced on Thursday.

The 22 caves have a total length of 11.7 kilometers.

Of the total, 20 caverns were found in Lam Hoa Commune under Tuyen Hoa District and Hoa Phuc and Hoa Son Communes under Minh Hoa District.

The remaining two caves were discovered in Phong Nha-Ke Bang National Park.

The newly discovered grottos were mostly wet and relatively unique in comparison to other caves found in Quang Binh, according to a British Caving Association expedition team.

In particular, Son Doong, En, and many other caves have only one main entrance while the newly discovered cave system has multiple entrances and exits.

Some of the caves are interconnected, creating multiple cross paths that make exploration considerably intriguing.

Quang Binh will need more time to formulate a plan allowing it to sustainably use the caves for tourism purposes, according to the management board of Phong Nha-Ke Bang National Park.

The British Caving Association also discovered five new caves untouched by humans in Quang Binh Province last month.

They have a total length of 3.34 kilometers and are wet caves.

Quang Binh is dubbed Vietnam’s 'Kingdom of Caves' with over 400 caverns found.

Of them, Son Doong is the largest natural cave in the world and En is the third largest.
