Hang Son Doong: Discover the largest cave in the world where you can fit 2 jungle and fly a Boeing 747 through its passages

Hang Son Doong, the world’s largest cave in Vietnam, was discovered in 1990 and is a breathtaking natural wonder. Formed over millions of years, this massive cave features towering stalagmites, ancient marine fossils, and even its own internal jungles, thanks to massive skylights that illuminate its depths. Recent discoveries, including an underwater tunnel, continue to expand its already immense size.
