Yǐn yán: Lónggāng lóng gāng, yún duān láng qiáo. — At Longgang the “Dragon Jar” opens, and a glass bridge floats out over the abyss.
Longgang — the name means “Dragon Jar” (龙缸) — is a 5A geopark in the remote southeast of Yunyang County, built around one of the most arresting landforms on the Yangtze’s upper reaches. The centre of the park is a near-vertical karst sinkhole: a giant natural stone jar, roughly circular, whose walls drop straight down for hundreds of metres into a green-shadowed bowl of rock. Locals have called it the “Earth’s Jar” for centuries, and standing at its rim you understand why — the cliff edge simply ends, and the eye falls into a depth that the mind keeps trying to measure and cannot. The whole park is a country of limestone: karst peaks, blind valleys, sinking streams and caves worn smooth by water that has been at work here for tens of millions of years.
The headline attraction is the Cloud Sky Glass Bridge (云端廊桥), a cantilevered walkway that reaches straight out from the cliff face into open air with nothing beneath it. The deck is glass, so that every step shows the drop directly underfoot, and the structure extends more than twenty metres beyond the rock with a fall of 700 metres plus to the bottom of the gorge. On a clear day the view runs out over layered blue ridges; lean on the rail and the wind moves through the gaps in a way that makes the engineering feel both daring and calm. It is the kind of thing you do once on your knees and once on your feet, and by the third look you are simply grinning. Below, the Shisun River (石笋河) threads the canyon floor, a thin silver line that gives no sense of the height until you trace it upward with your eyes.
Beyond the bridge the park rewards slower exploration. There are show caves lit for visitors, with stalactites and underground streams; there are canyon trails along the Shisun River where the light comes down in narrow shafts; and there are quiet overlooks above the Dragon Jar itself, where a low wall is all that separates you from the drop. The air in the gorge is cool even in summer, and the stone holds the damp smell of deep water. Reaching Longgang takes time — it is a long drive from Yunyang’s county seat, deeper into the hills than most Yangtze tourists go — but that distance is part of the appeal: you come to a place that feels at the edge of the map, where the geology is the whole point and the only crowd is the wind. Bring a head for heights and a camera with a steady hand; the photos are the easy part, the standing still is the hard part.
