Cape Town - Remember that amazing footage of Hang Son Doong cave we recently shared with you?
Well, we've just stumbled upon yet another Vietnamese cave that will blow your mind!
Located in central Vietnam, the Hang En cave, is home to the Rao Thuoung River, which surges up to 91 metres in the rainy season, covering large parts of the cave.
However, as soon as the drier seasons hit, the water recedes, revealing an heavenly world of subterranean beaches!
