Helankou Deep Gorge Trek

The Helankou Deep Gorge Trek continues past the ticketed boardwalk of the Helan Mountain Rock Art Scenic Area in Helan County, using the same entrance reached by the seasonal Tourism Line 2 bus from Yinchuan or a roughly one-hour taxi ride. Where the maintained boardwalk ends near the main rock art panels, this route continues on foot into the unmarked upper gorge, covering about 15.9 km beyond the tourist area with around 664 m of cumulative elevation gain. The surface changes quickly from boardwalk to loose scree, gravel wash, and rocky stream bed, with no trail markers past the museum area, so navigation becomes the main technical challenge rather than steep climbing. Exposure increases as the gorge narrows, with rock walls blocking wind in places but offering no shade for long stretches, and no maintained shelter anywhere along the route. Landmarks are natural rather than built: successive narrowing points in the gorge, dry waterfalls to scramble around, and side canyons that can be mistaken for the main route without a GPS track or map. A sensible turn-around point is roughly the halfway mark, where the gorge narrows significantly and route-finding becomes harder; hikers unfamiliar with the terrain should not push further without local knowledge. There are no water sources, refuge huts, or emergency services past the museum area, making this a self-sufficient trek rather than a casual extension of the boardwalk walk below.
