Glass walkways on mountains are all the rage at China's Tianmenshan National Park, where the third walkway—hugging a mountain about 4,600 feet above sea level—opened August 1.
The Coiling Dragon Cliff walkway is about 300 feet long, and just 5 feet wide. Even if the walkway were made of wood, metal or concrete, the views of the park would be gorgeously vertigo-inducing. The glass only adds to the effect.
The national park's glass walkways and mountain views are popular with tourists, according to People's Daily Online.
The new walkway was previously wooden, according to Mail Online, but was converted to glass.
The two previously opened glass walkways include a bridge suspended 3,500 feet in the air.
Dizzyingly high glass walkways are also popular in Shanghai, where a handrail-free walkway on Jinmao Tower recently opened. And across the Pacific, Los Angeles is just getting started with a glass slide attached to the side of a skyscraper.
