We're not talking about the luxury brand, but the glass box that stands 12,604 feet over the rocks to give you a 360 degree view from Europe's tallest peak. Engineers have assured visitors about its structural durability and the technology that prevents this box from toppling off the edge. But is that enough?

Racing heartbeat, heavy breathing, nausea, trembling, chest pain, a sense of impending doom. These are the symptoms someone who's afraid of heights might be struck with if we brought them to this spot.

Arrayed below and before him would be the snowy summits of the French Alps including, to the south, the mighty Mont Blanc - Europe's highest mountain. He might not want to look down, but if you were to direct his head that way he would see below his feet a sheer drop of 12,604ft. Just a thin sheet of reinforced glass stands between him and oblivion.
6. Mount Huashan, China
Visitors flock to this mountain in China which is famous for its almost vertical stair cases, steep edges, and the creaky wooden planks that are bolted onto the sides of the mountain.

Situated in Huayin City, Mt. Huashan is 120 kilometers (about 75 miles) from Xian. It is famous for natural vista of steep and narrow paths, precipitous crags and a high mountain range. Its five peaks are the representative attractions and each has its distinctive charms: East Peak is the best place to enjoy the sunrise; South Peak has the highest altitude; West Peak is the most elegant; North Peak is famous as the Cloud Terrace Peak and Middle Peak is also called Jade Lady Peak.

The Mountain is also home to several influential Taoist temples, where many emperors of past dynasties took part in Taoist activities and sacrificed to the god of mountain, making it a holy land of Taoism.
