Son Doong Cave, or Tham Sein Dong, the world's largest cave located in Vietnam, is situated in Phong Nha-Ke Bang National Park, Quang Binh Province, near the border between Vietnam and Laos. Within this national park, there are still many areas that explorers have not reached, and exploration is only possible during the dry season. Son Doong Cave (Sein Dong means 'Mountain River Cave') in Vietnam is an ancient cave estimated to be 2-5 million years old, hidden within a valley. It was discovered by a local in 1991, but no exploration took place due to the villagers' fear of strange sounds coming from inside the cave. It was not until 2009 that a British expedition team ventured in and found that the strange sounds were caused by the flow of water inside the cave. Furthermore, the cave's interior boasts an environment that is breathtakingly stunning, like another world untouched by humans, with its own jungle, stalactites, stalagmites, and cave pearls.
