Recently, the South China Morning Post (SCMP) of Hong Kong (China) honored Vietnam's Son Doong Cave as one of the 7 most beautiful underground attractions in the world.
An article in the SCMP newspaper reviews the journey to discover the world’s largest cave. During a trip to the forest in 1991, farmer Ho Khanh discovered the cave’s mouth. However, the sound of rushing water and strong winds prevented him from continuing into the cave. The next times, he could not remember the location of the “mysterious” cave.
In 2007, when the British Royal Expedition conducted a search for a new cave in Phong Nha - Ke Bang, he also led the team to search for the cave for 2 days but did not find it. In 2008, Mr. Khanh found the location of the cave entrance again and contacted the British expedition team.
Through measurements, explorers confirmed that the cave is 5 km long. In addition to the underground river and lake system, the thriving jungle ecosystem, 400 million-year-old fossils and spectacular geological layers, Son Doong Cave is also home to a number of plant and animal species that exist nowhere else on Earth. In 2018, a team of British cave experts discovered that Son Doong Cave is at least 30% larger and much deeper than previously believed.
In addition to Vietnam's caves, the list of the world's 7 most beautiful underground attractions also includes Tham Luang Cave (Thailand), Paris Catacombs (France), Cold War bunkers (Albania), Reed Flute Cave (China), Malinta Tunnel (Philippines), and the British National Coal Mining Museum.
