The stomach-turning SkyBridge, near Sochi in south-western Russia, stretches for almost one kilometer and can take 30,000 people at a time.
And extreme sports fans who have not had enough highs for one day can speed along a zip wire more than 500ft above the valley floor.
Known as the Trollwire – riders are strapped to a zip wire horizontally side by side – it reaches speeds of 70mph as it swoops through the air.
