Spain's most terrifying mountain path recently re-opened to the public after being closed following a series of deaths in 1999 and 2000. It may now boast more safety features but the path, snaking along the side of a gorge in El Chorro in Malaga, is still not one for the faint hearted! It was voted one of the best new attractions for 2015 by Lonely Planet.

If regular old skiing and snowboarding are too tame for you, why not try your hand at something a little bit more extreme - heliskiing.
