Wujiang Source Hundred-Mile Gallery (Dongfeng Lake)

The largest canyons within Zhijin Cave Scenic Area are the Luojie River Canyon, Nagai River Canyon, and the Yachi River Canyon formed at the confluence of the two rivers. After the state built the Dongfeng Reservoir in the 1980s, a long, three-pronged lake came into being. Named after the original place names, it is divided into three lake areas: Luojie River Lake Area, Nagai River Lake Area and Yachi River Lake Area, collectively known as the Wujiang Source Hundred-Mile Gallery.

Although Dongfeng Lake was formed by a man-made reservoir, its banks are entirely lined with karst gorges well preserved in their original form, so it is still categorized as a natural scenic spot.

Luojie Lake stretches 62 kilometres, with a width ranging from 80 metres to 500 metres. The cliffs on both banks rise between 100 and 400 metres high. The whole landscape is magnificent and imposing. Eroded by ancient water ripples, rock seepage as well as wind and rain, the cliff faces have developed into colourful and ever-changing natural stone murals. A great variety of cliff-dwelling plants grow thickly on the rocks, creating endless picturesque views of plateau lakes enclosed by steep mountains.

Dongfeng Lake boasts abundant aquatic resources. The most famous species include sturgeon, a Class I national protected wild animal; tender and delicious fine-scale silver carp; yellow catfish; and whitebait, an introduced species that now reproduces naturally in the wild.

Major natural attractions in Dongfeng Lake Scenic Area include Heavenly Bamboo Peak, Lower Red Cliff, Moon Rock, Vast Universe Rock, Golden Spear Rock, Sleeping Beauty, Eight Immortals Cave, Fairy Water Bay, Huawuji and Tiger Gate Pass.

Half a kilometre southwest of Red Cliff Wharf lies a large spring called Longtan Mouth. It has a stable discharge of 0.6 cubic metres per second all year round, with clear and high-quality water forming a three-tier waterfall. Local villagers built primitive water mills driven by the spring current to grind wood powder for incense cakes, which are well worth seeing
