Descending into the deep: The famous Helix walkway winds its way down between massive, moss-covered rock walls. The final reward at the end of the trail – a spectacular 50-meter-high waterfall crashing down into a natural pool at the base of the gorge. Meet Liechtensteinklamm (Liechtenstein Gorge) – deep, 4-kilometer-long alpine gorge located near St. Johann im Pongau in the Salzburg region of Austria.
