Bidukou Qilian Mountains Gorge Walk

The Bidukou Qilian Mountains Gorge Walk follows a deep canyon through the eastern Qilian Mountains in Minle County, Zhangye, Gansu, China. Bidukou, also known as Bidu Pass, lies on the road from Minle toward Qinghai, and the upper sections rise above 3,000 m. Trailhead access is by taxi or private car hire from Zhangye, which takes about 2 hours, and public transport to the gorge is limited, so visitors usually arrange a driver for the day. Parking is informal beside the road or at the start of the gorge path, and visitors should check locally whether any entrance fee or permit applies. The route covers about 5-10 km of gorge and river path, with the exact length varying by season, and takes 3-5 hours. Elevation gain is moderate but the altitude makes climbing slower, so the walk rates as moderate overall rather than easy. Technical difficulty is low to moderate, with some stream crossings, loose stones and narrow sections beside the river. Surfaces include packed dirt, gravel, rock and damp ground, and high water after rain or snowmelt can cover parts of the path. The gorge has river, forest and alpine meadow sections, giving shade in the forested stretches and open exposure higher up. Key landmarks include the river itself, the steep gorge walls, wooded slopes and the alpine meadows near the top. Weather turns fast at altitude, and the road beyond may close in winter snow, so a sensible turn-around is the point where cloud builds or the path becomes wet. Water should be carried, because river water is not safe to drink untreated. There are no huts on the walk, and services are sparse beyond the nearest roadside stops, so food and warm clothing should be packed. Phone coverage may drop in the gorge, so visitors should tell the driver or a contact their intended route and return time. A rain jacket and warm layer are important even in summer.
