Anyone afraid of heights should probably give this walkway a miss - because at 1,500ft above a glacier it could be 'the world's scariest bridge'.
The Titlis Cliff Walk in the Swiss Alps took five months to build and is thought to be Europe's highest suspension bridge, at a stomach-turning 9,800ft (3,000m) above sea level.
The structure, which cost £1million to build, is a whopping 330ft long, but only 3ft wide.
And on the Titlis Cliff Walk's grand opening, a huge snow storm reduced visibility to just a few feet - leaving visitors with no idea of what lay beneath them.
The impressive bridge on Mount Titlis was built to celebrate the 100th anniversary of the opening of a cableway which joined the towns of Engelberg and Gerschnialp in January 1913.
Construction work was an extreme challenge for engineers, with working hours determined by the weather conditions.
Peter Reinle, from Titlis Cable Cars, said: "Everyone was very impressed by the bridge.
"It opened in a real snow storm which made it an adventure for everyone who crossed it."
