This is called 'khawh pawp'. It is said that the strong current of the water creates a hole in the cliff, which makes this beautiful waterfall. Located in Aizawl, Mizoram, India. Photographed by Muana Leo Khawlhring.
I don't know what's more interesting: the fact that the largest cave was hidden from the world until or the fact that it has a small jungle and a fast moving river inside of it. Son Doong cave is located in Phong Nha-Ke Bang National Park of Vietnam.
