Hang Sơn Đoòng is more than just a cave; it is a hidden ecosystem. This natural wonder, located in central Vietnam, has topped measurements by volume for a cave passage. At over 5 kilometers long, 200 meters high, and 150 meters wide, it calks the comparative wide open space of a city block.

The cave is also home to a river, massive stalagmites, and cave pearls the size of baseballs.
A Secret World Within the Earth
Local stories describe how the cave was discovered and its geological timeline is enriched by the detail that the sections of the cave ceiling collapsed up to 440,000 years ago, allowing sunlight to penetrate to the floor and create an environment for plants to grow—now a rainforest.

Following the discovery, Ho K'un eventually located the cave again in 2008. A solicited British and Vietnamese expedition also followed, identifying and exploring the cave as a world wonder; all in all, it was only revealed to the outside world in 2009 The cave has at least 400 other sections of cave passage to it. Exploration continued to be met with difficulty due to the presence of a large hole in the cave that required specialized equipment to handle the climb.
