Cliff walking : Dubbed the world's deadliest hike the Huashan mountain trail in China is not for the faint hearted. Tethered to a safety line on the rock face hikers make their way across wooden planks and sheer cliff edge to reach one of the world' s most remote tea houses over 2000m high. There are plenty of other (slightly) less pant wetting paths around the world like the Caminito el Rey in Spain which underwent a hefty restoration in 2015.
High altitude urban experience : Adture activities are often thought to be the remit of the great outdoors but thrill seekers can get all their kicks without venturing to the sticks. Many cities offer high altitude adrenaline pumping tours from abseiling off famous buildings to walking around the outer edges of iconic skyscrapers attached to a safety wire. New Zealand's Auckland Sky Tower and Toronto' s CN Tower both offer tours around their heady heights. Alternatively try abseiling 100m down Rotterdam' s Euromast. I cried real tears on the CN Tower EdgeWalk. But honestly it was life changing and there' s not really much I' m scared of anymore. Lauren Finney US Magazine Editor at Lonely Planet.
