Huangguoshu Behind-the-Falls Water Curtain Cave

The Water Curtain Cave (Shuilian Dong) at Huangguoshu Scenic Area in Zhenning County, Anshun, Guizhou province, is a cave passage of more than 100 m that runs behind the curtain of Huangguoshu Waterfall, one of the largest waterfalls in Asia. Visitors walk through the passage along the cliff, with several windows opening onto the cascade, so that the full width of the falling water, the roar and the spray are experienced from behind and at close range. It is the signature close-up experience at Huangguoshu and one of the best-known waterfall walks in China.

The activity is graded easy. The passage is short, taking roughly 20-40 minutes including viewing stops, and the walk involves wet steps and slippery rock but no technical skill or special fitness. Children and older visitors can usually manage it with care, though the stairs down to the falls and the climb back up add effort. There is no formal age limit, and parents should keep a firm hold of small children near the wet openings.

No specialist equipment is required, and entry is included in the Huangguoshu ticket, around CNY 160-180 in peak season. Visitors should bring a rain poncho or waterproof jacket, non-slip shoes, a light layer and a waterproof camera or phone cover, because spray soaks clothing and electronics near the viewing windows. Payments at the scenic area are commonly made by Alipay or WeChat Pay, so cash or a mobile payment method is advisable.

The operator is the scenic-area staff, who manage the paths, handrails and viewing points. The passage is a managed, well-marked route with staff stationed nearby, and safety is based on staying behind handrails, avoiding slippery edges and following any closure notices. When flow rises sharply after heavy rain the cave may be closed temporarily, and staff handle evacuation back to the main paths.

The site can be visited all year, but the flow is greatest from July to September, when the falls are at their most powerful and the cave is wettest. Winter flow is lighter and the passage is cooler and quieter. National holidays and summer weekends bring crowds, so early arrival is helpful. Dry spells give the safest footing, while very high water can close the passage.
