As Malaysian, I am familiar with the muddy (like Milo or teh susu coloured) lake or pond and occasionally we will see clear water lake. This is the first time I see such a scenic and beautiful multi coloured lake. Really an eye opening experience.
The Colourful Lake or Five Flower Lake (五 花海) is a multi coloured lake whose bottom is criss-crossed by tree trunks. The lake is 5 meters deep (elevation 2,472 meters).
This lake is the pride of the Jiuzhaigou area. Due to the varying depths of water and the formation of silts on the bottom, the lake's waters assume a variety of colors, such as light yellow, dark green, deep blue etc.
Despite the huge crowds of tourists, Jiuzhaigou remain very clean and free from rubbish. Smoking is strictly prohibited here. No flower/leaves/plants plucking nor feeding the wildlife or fish.
