Lake of Mirrors

(Local Name: Jingpo Hu) Covering an area of 95sq.km/37sq.mi and situated 10km/6mi south of Bohai at a height of 350m/1150ft, the Lake of Mirrors is of volcanic origin. Deposits from an erupting volcano blocked the upper reaches of the Mudan river and resulted in the formation of the lake. At its northern end a 40m/130ft wide waterfall plunges down 20m/65ft into the lake, which is surrounded by a string of ten craters. At the bottom of four of them grow all sorts of different trees, forming what is known as the Underground Forest (Dixia Senlin).
