The name translates as East Lake, but Dong Ho is not a lake but an inlet of the sea. Dong Ho is said to be most beautiful on nights when there is a full or almost-full moon. According to legend, on such nights fairies dance here.
The ‘lake’ is just east of Ha Tien, bounded to the east by a chain of granite hills known as the Ngu Ho (Five Tigers) and to the west by the To Chan hills.
