The biggest cave in the world is Sơn Đoòng cave in Vietnam. It has a volume of nearly 40 million cubic kilometers. Inside, there’s a river, two jungles, and a localized climate.

It was discovered in the early 1990s, and nobody returned until 2009. A man named Ho Khanh first found it while hunting—he’d heard wind and the flow of the river inside. However, on return trips, he couldn’t find the cave again. He searched for it for years before he finally led researchers to it more than a decade later. Now, a limited number of people can explore it each year.

Biggest cave in the world is Hang Son Doong. And it is located right in the heart of Phong Nha-Ke Bang National Park in the Quang Binh province of Vietnam.
