The US Newspaper CnTraveller said "Vietnam's Son Doong Cave, the largest cave in the world, could hold an entire city block of Manhattan - including 40-story skyscrapers. It has its own lush vegetation where sunlight filters in from sinkholes above, and clouds even form near the ceiling when moisture condenses there. In other words, it's practically its own little world lurking under the earth's surface."

Son Doong Cave has been listed in the top of destinations by international newspapers such as Business Insider, Buzzfeed, Smithsonian...
