Discovery
Nuoc Nut was discovered in 2003, long before nearby Hang Va. A connection between the two was discovered in 2016. There seems to be no physical connection with Son Doong, though they probably share the same underground water flow. Nuoc Nut is 2.2km long and is probably about 2 million years old.
