Diving expedition in underground river in Son Doong Cave


The professional divers from British Cave Research Association supported by Oxalis Adventure have just come back from their diving expedition in the underground river inside Son Doong - the world's largest cave. What they have found is shocking!

About this diving expedition: A team of British divers have dived the terminal sump of Hang Son Doong with support from Oxalis. In extremely challenging conditions, the sump was dived to a depth of -77m making it the deepest cave dive in Vietnam. The cave was also extended by a further 60m despite the difficulties of route finding in very poor visibility and the significant depths.
