Just before reaching Sohra, a road to the right, leads one to the falls which is 5 kms away. The waterfall derives its name from a Thlen or a snake of gigantic size which dwelt in a cave. Legend has it that the people destroyed the snake in order to rid themselves of its reign of terror. Adjacent to the very spot where the Thlen was slaughtered lies the Dain-thlen Waterfalls. Natural rock carvings of the epi­sode draw visitors to see the image of the Thlen, the symbol of greed, cor­ruption and evil.
