Multi-color Lake (elevation 2,995 meters) covers an area of 5,645 square meters, with a depth of 6.6 meters. It is situated below Long Lake and deeply hidden among the highly elevated forests.

Multi-colour Lake, the quintessence of the whole Jiuzhaigou, is full of aquatic biological species, such as sponges, algae, and ferns. In addition, there are many herb-like reeds and plants growing in the pond. Because different plants in the pond contain different levels of chlorophyll, they present different colours in the water, with a high consistency of calcium carbonate. The pond is an exquisite patchwork of different colours; light green, milky white, bright yellow and pale blue. Visitors can experience a splendid view of this amazing scenic phenomenon.
