Overview
Archive NoteSon Doong Cave lies within Phong Nha-Ke Bang National Park in Viet Nam and is one of the property's most significant large caves.
UNESCO's World Heritage Centre currently states that Son Doong contains the world's largest documented cave passage in terms of diameter and continuity.
This record is deliberately limited to that criterion. Specialist cave research has discussed different results for other geometric measures such as maximum cross-sectional area, so this entry does not generalize the claim to every meaning of 'largest cave'.
Son Doong was first systematically explored and surveyed in 2009.
