From east to west, it measures 8 kilometers, starting from Baidicheng and ending at Daixi township. With vertical cliffs of some thousand meters high as its two flanks, the Qutang Gorge is only a few dozens of meters wide just like a narrow gateway. With swash and rumble, the surging Yangtze River pours into the gateway with great momentum. Looking up towards the tops of towering precipitous mountains along the Gorge, one sees from a boat only a narrow strip of clouds and sky, but under foot the River tears on violently.
