Cloudy Lounge Bridge-----It is the world’s longest glass cantilever bridge, 26.64 meters long and built at an altitude of 1,010 meters. You can look down to view a vertical drop of 718 meters to the ground below. There are no steel supports directly below the walkways of the horseshoe-shaped viewing floors and guardrails are all transparent pieces of glass to allow you an unobstructed, and stunning panoramic vista.

The geological park also has a couple of caves, such as the Dragon Cave and the Daan Cave, filled with natural mineral deposits and neon lights for an enhanced visual effect that makes it perfect for exploration.


The park is home to the world’s largest glass cantilevered bridge, one of China's many engineering triumphs. Walking on the bridge is not for the faint-hearted as it has no steel supports, but it does give you a feeling of floating above the wonderful landscape.
