Megan gazes up to a sky hole in Hang Son Doong, Vietnam. The opening is more than 100 meters higher than the unique spiral stalagmite she is standing on. The cave walls here are sheer cliffs and there is no way out. The light and rain entering the hole in the cave ceiling fosters growth of low-light plants, ferns and moss.

Inside Hang Son Doong, the world’s biggest cave, the size of the caverns is on another level. Without a caver for scale it is hard to portray just how gigantic the cave is.

In Hang Son Doong, Vietnam, the world’s biggest cave, overlooking the path leading into an underground forest that flourishes under a massive collapsed section of the cave ceiling, many kilometers from the entrance. A temperature difference of around 15 degrees celcius between the air inside and outside the cave causes mist and clouds to form.
