CHINA'S TIANMEN PARK GLASS WALKWAY
Now, who hasn't wanted to hike a trail a mile up the vertical drop of a mountain on a platform of glass? This new walkway in Tianmen Mountain National Park in China measures 200 feet (61 meters) long and is about 4700 feet in the air. The pants-shittingly thrilling walkway joins the west cliff at the Yunmeng Fairy Summit, where Tianmen Mountain and Zhang Jiajie meet. The park takes such pride in their walkway, that visitors are requested to wear shoe covers to keep the glass transparent and clean.
