A Whole New World Discovered By A Farmer After Seeing A Hole In The Rock
At more than 200 meters tall, it fit a 40-story high-rise inside. What's more, at more than 150 meters wide, it could comfortably hold a 747. Vietnam's Hang Son Doong is the biggest cave in the world, and taking a visit is basically remarkable.
Art Work Which Is Present In Most Of The Caves
Many caves contain relics from the past, such as paintings on the rock walls. But nothing of the sort has been found in this cave.
The First Visitor
The first visitor toured this cave in 2013 and found so many things which were never seen.
