More than half of the scenic area is covered in virgin forests, with bamboos, flowers, and is home to such rare animals as giant pandas, golden monkeys and white-lipped deer.

Waterfalls and streams link 108 lakes of various sizes, many of which are classic ribbon lakes at the base of glacially formed valleys. Also of note are a number of large and spectacular waterfalls, including Xionguashai (Panda Lake) Fall which drops 78m in three steps, and the Zhengzhutan (Pearl Shoal) Fall, which drops 28m in a broad curtain of water, 310m wide. At the end of the Zechawa Valley is Changhai (Long Lake), discovered in the 1970s. It is the largest lake in Jiuzhaigou. With an elevation of 3,000 m, the Changhai area is covered in snow all year round. It is especially pleasant to boat on the lake in summer. In spring, the lake mirrors the flowers on the snow-capped mountains. In autumn, it mirrors the red and gold maple leaves. In winter, it is covered with ice.

The numerous lakes in Jiuzhaigou Valley have evoked religious feelings in the local residents and given rise to many enchanting folktales. According to legend, the goddess Wonosmo dropped a mystical mirror, a gift of love from the god Dag here, and the broken pieces became the 108 lakes. The colorful lakes in Zechawa Valley are said to be the Jasper Lakes of the Queen Mother of the West. According to a local saying, the lake water was colored by the cosmetics of fairy maidens, although it is more likely something to do with the aquatic plants in the lakes. Legends and more recent stories abound concerning the existence of monsters in various lakes, notably Changhai (Long Lake), Jianzhuhai (Arrow-Bamboo Lake) and Nuorilang Lakes. One of these lakes, Wolonghai or Dragon Lake, has a calcareous dyke running through it clearly visible below the water surface, which, in local folklore, has been compared to a dragon lying on the bottom. These stories are a further attraction to tourists and have received some scientific interest.
