Legend tells that three girls, who were once journeying on the sea, came to the grotto to take shelter from the rain. They were so engrossed with the beauty of the grotto, that they did not notice the rising tide. They drowned, only to become water goddesses.
Quang Quang Quang Hanh Grotto is extremely beautiful. A small boat will take you through the stone passageway by flashlight, casting magical colors on the hanging stalactites.
