Video: A Journey Through The Largest Cave on Earth

Located in a remote corner of Vietnam, Son Doong Cave is the largest cave system in the entire world, stretching out for more than 5 km (3.1 miles) underneath the surface of the Earth. But it is not just its length that is impressive, as the massive cave features a series of chambers that are a sight to behold. In this fantastic video we'll delve deep underground to witness this place for ourselves.
