A total of 57 new caves have been discovered in Vietnam’s Quang Binh central province, the Vietnam News Agency (VNA) reports.
A team of explorers from the British Cave Research Association (BCRA) is currently studying the region, which is home to the world’s largest cave. Son Doong stretches 9km in length, is 200m high and up to 150m wide.
The “new” caves discovered this year have a combined length of more than 20km, and include Hoa Huong (2,876m), Tien 2 (2,519m), Bom (1,500m), Dinh 1 (1,430m) and Ruc Ma Rinh 2 (1,360m).
The findings were revealed by BRCA team leader Howard Limbert at a recent press conference in Vietnam. The explorer also noted that several of the caves would be suitable for adventure tours.
This year’s expedition was the BCRA’s 17th exploration of the area since 1990. To date, the British team has surveyed 311 caves of all sizes, including Son Doong which was surveyed in 2009, when it was officially registered as the world’s largest cave.
