The Son Doong Cave is so large, that some of have claimed it can fit an entire New York City block.
The length of the cave is 5 kilometers (slightly over 3 miles). Some of the sections were measured to be as high as 200 meters tall and 150 meters wide. Not to be outdone, the world’s tallest stalagmites are said to be found here. Some of them were believed to be measured at 8 meters or well over 200 feet tall.
