The Dashiwei Tiankeng Glass Viewing Platform is the highest viewing platform in the world. Overlooking the 2nd deepest Tiankeng in the world, the tourist overlook allows guests to look down the side of one of the tallest sheer cliff drops in the world at over 500 meters.

Only discovered in 1998, the Dashiwei sinkhole is one of just 75 such depressions in the entire world with approximately 50 of them located in Central China. Most Tiankengs have rivers at the bottom that travel between underground caves. The deep hole formed when the river gouged out the rock surroundings above leaving a spectacular void 600 meters long and 420 meters wide with a height of between 511 and 613 meters.
