The Elephant Trunk Hill is not only one of the sights of Guilin, but also the symbol of the city. It is basically a large lump of rock with a big hole in it. It looks like an elephant standing on the bank of river and taking water with its trunk. The hole is 17 meters long, 9.5 meters wide and 12 meters high. At night the water beneath the hole mirrors the moon. It looks as if the moon is floating on the water. This view is referred to as 'Elephant Hill Fixing the Moon'.
