The Anjihai Grand Canyon, also known as the Hongshan (Red Mountain) Grand Canyon, is found at the northern foot of the Tianshan Mountains in northwest China's Xinjiang Uygur Autonomous Region. Together with the winding Anjihai River, they form a colorful geographical splendor. The canyon stretches about 30 kilometers in length, with a depth of up to 400 meters. The narrowest part is only two to three meters.
