Drone explores Son Doong Cave, one of the world’s largest caves, for first time ever
And the footage is absolutely mesmerizing.
Son Doong Cave (AKA one of the world’s largest caves) was originally discovered in 1991 by a local Vietnamese man named Hồ-Khanh. However, fear of the sounds from its underground river prevented any exploration. It wasn’t until 2009 that British scientists embarked on an expedition to fully explore this mammoth cavern. Their findings are incredible. They would have explored further but a large calcite wall stood in their way.
