Spectacular karst and large caves are known from central and northern Vietnam, e.g. in the Phong Nha/Ke Bang area (Laumanns 2010b). However, the small caving areas of southern Vietnam, developed not only in carbonate karst but also in volcanic and granite rocks, have not attracted many speleologists up to now. Apart from biospeleological and a few touristic activities (Addis 1970, Deharveng et al. 1995, Price 1995) the rich diversity of caves in south Vietnam (Ha Tien/Hon Chong area in Kien Giang province) was first investigated systematically by a German–British team in 2010, followed by a 2011 lightweight German–British expedition to Kien Giang and Da Nang provinces. This has resulted in the present publication, which describes more than 60 caves with a total of 4,318 metres of surveyed underground passages. This publication strives to encourage other speleologists to continue with cave exploration in south Vietnam as this compilation is regarded as being far from complete with regard to the karst and caves of south Vietnam.
