The Emerald Valley extends 6km at the foot of the Xiandu Mountain, which lies at the northern end of Mt. Huangshan. Up the terraced mountainside are strewn glittering green pools various in shape and size. With the constant change of light, the water changes its color into all shades of green, hence the name Emerald. The riot of color presents a kaleidoscopic scene. Rare waterfowls such as white swans and mandarin ducks are found in the valley. And as mandarin ducks symbolize love, the place is called Love Valley by the local people.
