This lake has such romantic connotations for the Vietnamese that you would think it was created by a fairy godmother rather than French dam work. Legend has it that a 15-year-old girl named Thuy drowned herself after her boyfriend of the same age, Tam, fell in love with another. Her gravestone still exists on the side of the lake, marked with the incense and flowers left by other similarly heartbroken souls, even though the name on the headstone reads "Thao," not "Thuy." The place is crammed with honeymooners in paddle boats and motorboats.
