The Zechawa Valley is the south-eastern branch of Jiuzhaigou. With the length of 18 kilometers, the Zechawa Valley is the longest and highest touring line from Nuorilang to Long Lake. Here you can get a panoramic view. The scenic spots along the valley mainly include Long Lake, the Seasonal Lakes, Five-Color Pond.
Long Lake is the highest and largest and deepest lake taking in the shape of crescent. The source of the lake is melted snow from the mountains. Surprisingly, the lake never dries up in the dry season of winter and spring and never overflows its bank in the rainy season of summer and winter, and there are no outgoing waterways in the Lake. According to folklore, a monster live in the depth of the lake which adds the mystery to the lake.
Seasonal Lakes are a series of three distinctive Lakes (lower, middle, upper) along the main road. The lower Seasonal Lake is in the vicinity of Zechawa Village and grows a grove of birches at the lakeside. The middle Seasonal Lake is surrounded by woodland and looks like a sapphire at the distance. The upper Seasonal, next to Five-Color Pond and surrounded by cliffs, is said to be the place where dragons live, so it is also called Dragon-hiding Lake. The lakes changes from the empty to the full in a year.
Five-Color Pond is the smallest but most splendid lake among Jiuzhaigou lakes. Rising 2,995 meters above sea level, the Five-Color Pond takes an area of 5,645 square meters. It never freezes over in the cold winter due to recharge water from Long Lake. It is notable for its richly colored underwater landscape and brightest and clearest waters.
