The Overhanging Great Wall (悬壁长城) is a section of the Ming Wall that climbs steeply up a ridge north of Jiayuguan, approximately seven kilometres from the main fortress. The name comes from the angle of ascent — the wall goes up the ridgeline at a gradient that makes it appear to hang vertically when viewed from below. The climb to the top section is genuinely steep and takes about 20 minutes each way; the views from the summit watchtower extend across the Hexi Corridor in both directions and give a sense of how the wall functioned as a surveillance system across the desert plains.
The section also shows how the wall adapted to different terrain — the valley sections are broad earthen ramparts, while the ridge climbing uses narrower construction with the wall essentially clinging to the rock. From the top, you can see the Jiayu Pass fortress to the south and, on clear days, the Qilian Mountains rising beyond it. A cable car operates alongside the wall for visitors who prefer not to climb.
