Phenomena packed St. Johann in Salzburg is also home to the Liechtenstein Gorge, only the longest, deepest and most dramatic in the entire Austrian Alps. Closed for the past two years, it’s set to reopen for summer 2019, just in time to take kids on one of the most mesmerising walks of their life. At some points the gorge snakes ribbon-like between immense towering rocks leaving only a sliver of sky in sight. At others it’s a romance of vivid green vegetation showered with rainbow-coloured mists. Slightly more than a kilometre of the gorge is accessible on a network of wooden walkways and bridges. And if kids need an incentive for their legwork, the big reveal of Liechtensteinklamm Falls at the end of the route is awesome.
