According to The Travel, Son Doong is known not only as the largest cave in the world with its unique beauty and structure, but also as the most difficult and dangerous cave discovered in Vietnam.
“Being 200m high and 175m wide as well as 9.4km in length, this cave is estimated to fit a 40-story New York skyscraper,” it noted.
The World Guinness Organization recognized Son Doong as the largest cave in the world in 2009. However, The Travel believes that Son Doong cave may be even larger than what was previously discovered as many theories suggest Son Doong cave is connected with other cave systems.
The nine other most incredible caves in the world are Vatnajokull Glacier Cave of Iceland, Naica Mine Cave of Mexico, Krubera Cave of Georgia, Glowworms Cave of New Zealand, Batu Cave of Malaysia, Marble Caves of Chile, Tham Lod Cave of Thailand, Reed Flute Cave of China, and Škocjan Cave of Slovenia.
