8Trift Bridge, Switzerland

However, this suspension bridge, spanning 170 meters across the Trift Glacier, is not for the faint-hearted. Hanging 100 meters above the glacier, the bridge sways with the wind, and the narrow wooden walkway provides a dizzying experience. While the Trift Bridge has been modernized and reinforced, its high altitude and exposure to the elements still make it a perilous adventure.
