Not far from Rizegou Guesthouse is the Swan Lake. It is said that swans used to reside here. At the present time, the lake remains semi-marsh land eith waterweeds fully covered on the surface. In spring the lake resembles a carpet of green grass; in summer the lake is splendidly decorated with blossomed flowers; in autumn the yelliwness in the lake meets the eye in every side; in winter the lake remains a world of ice and snow. Near the upper end of the lake is an another lake called Fangchaohai. The lake leads to hills where the hill peaks raise one higher than another. However, among the hills there is a pealk that obviously towers. It is named the Sword Rock because it looks sharp on the top and wide at lower part. Passing the foot of the towering peak, you start to walk into a dense primeval forwst, where you find yourselves deep in the boundless expanse of trdds and plants, feeling as light as if you had left the world of men and became immortal beings. There are an abundance of trees that looking up you hardly see the sunshine. Some of the trees curves down like awnings; some loom up like obelisks; some stand erect like men; some recline like dragons. Beneath your feet are soft mosses that grow in a thick furry mass on wet soil. When you walk through the forest, cool greenery rests your eyes, gentle breeze sooths your ears and the utter quietness refreshes your heart.
Wucaichi, 100.8m in length and 56m in width, is the smallest lake in Jiuzhaigou. However, it is commonly believed that it is richest in color. Someone says that it looks like an emerald inlaid inside the hills. Many visitors usually stop to sit by the lake and seem to feel ease at heart. The water is ruffled, and its azure translucence below the water stretches to the bottom before your eyes. you may look in amaziment at multi-colored clusters displayed at the bottow like inexhaustible treasures supplied by the Greator. Some visitors even doubt whether it is painted by the local peoplw. The water from Wucaichi neither increases nor diminishes. It soaks into the lake from Changhai Lake. As the sun xasts lights on the water, sekiments at the bottom act on the sense of algae and bryophyte plants and give rise to the multi-colorful clusters as it occurs in Wuhuaihai Lake.
After passing a col from Wucaichi Lake, you arrive at Changhai Lake which is licated at the top of Zechawa gully at 3, 100m above sea level. There are several questeins related to the lake. Hoe did the lake take shape? Why soes the lake have no exit? Is any fish in the lake? How long is the lake? Hoe deep is it?
The first question still remains a mystery. It is uncertain if it took shape due to esrthquakes, landslides or mud-rock flow. The source of the water comes from springs from the forests and snow on the mountains around. The way of draining off water in the lake is to evaporate and permeate into the ground. In the lake the water never overflows in summer, and it never dried up in winter. The lake has no fish probably because it is too cold in the lake. a legend says that a monster had eaten yp all the fish a long time ago. The lake is 7.5km in aength, and in some parts it is 103m i9n depth.
