Tiger Leaping Gorge in Yunnan Province, China

The upper reaches of the Yangtze River flowing through southern China are called Jinshajiang. Near Shangri-La City in Yunnan Province, the river flows down a narrow valley consisting of schists with a relative height of more than 3,000 m and a width of less than 100 m. The valley is called Tiger Leaping Gorge because even on a clear day the muddy water flowing down through the narrow section looks like leaping tigers. Visitors can see the muddy torrent close up as they walk down along the valley wall from the parking lot to the river side.
