The Zechawa Valley is the south-eastern section of Jiuzhaigou. 11 miles (18 kilometers) long, the Zechawa Valley is the longest and highest touring line from Nuorilang to Long Lake. Here you can get a panoramic view of the scenic spots along the valley, including Long Lake, the Seasonal Lakes, and Five-Color Pond.
Long Lake is the highest, largest, and deepest lake taking the shape of a crescent. The source of the lake is melting snow from the mountains. Surprisingly, the lake never dries up in the dry season of winter and spring, and never overflows its banks in the summer rainy season of summer, and there are no outgoing waterways in the Lake. According to folklore, a monster lives in the the lake, adding to the mystery of 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 where a birch grove grows nearby. The middle Seasonal Lake is surrounded by woodland and looks like a sapphire from 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.
Five-Color Pond is the smallest but most splendid lake among the Jiuzhaigou lakes. Rising almost 10,000 feet (2,995 meters) above sea level, Five-Color Pond takes up more than 60,000 square feet (5,645 square meters). It never freezes over in the cold winter due to the water from Long Lake. It is notable for its richly-colored underwater landscape and bright, clearest waters.
