This is the location for the Saisiyat Tribe; it is a lake surrounded by mountains at 738m above sea level with prosperous tree forests. There is often dense vapor on the surface of the lake, and this place appears even more charming with the magnificent sceneries and the tribal legend; it is also an ideal place to admire fireflies. When coming to this place, one may stroll along the lake side, where the reflected images of the high mountains and the sky on the surface of the lake are absolutely magnificent!
