World’s Largest Cave in Vietnam to be Explored by Divers Involved in Thai Cave Rescue and Local Adventure Tour Company Oxalis

Quang Binh Province, Vietnam (PRUnderground) October 22nd, 2018

A team of cave diving experts involved in the rescue of the Thai football team are preparing to visit Vietnam and dive a 600m unexplored river passage inside the depths of Son Doong Cave. This expedition is being organized by Oxalis Adventure Tours and members of the British Cave Research Association, who currently run treks into the cave for adventure enthusiasts.  

Howard Limbert, a member of the British Cave Research Association, and technical director with Oxalis Adventure Tours, said about the dive, “it will not be easy as it is a big river in a relatively small passage and hence the current will be strong”. It is expected that this small passage will connect to nearby Thung Cave which was explored back in 1994, and which also has a great river running through the cave. 

Thus, the team have invited four of the best cave divers in the world, Rick Stanton, John Volanthen, Jason Mallinson and Chris Jewell, who were all critical players in the cave rescue operation of the young boys in Thailand this past July, 2018. 

The diving team will also be joined by local caving expert Martin Holroyd, who is currently a safety guide on the current Son Doong Cave tourist expeditions, which are available to the adventurous public.

The team spent the past eight years trialing a number of different methods to determine where this passage leads, but it was decided that only with a dive could they truly explore and map this section of the cave. The date of the dive has now been confirmed for April 3, 2019, when river conditions are expected to be ideal. 

Son Doong Cave is currently the largest cave in the world by its size, but if this discovery turns out to be true, it will exceed the volume of Clearwater Cave in Mulu National Park, with a whopping 40.4 million cubic meters, clearly making it the biggest cave in the world. Limbert finished, ‘being the best divers in the world we really think they can be successful in joining these two caves hence making Son Doong Cave definitely the largest cave by both volume and size in the world.” 

Oxalis is seeking partners to assist with this research expedition, particularly media partners. Please send an email to contact@oxalis.com.vn if interested.
