Guide to three short hut-to-hut treks in the Zillertal region of the Austrian Tyrol: the 9-day Zillertal Rucksack Route/Berliner Hohenweg, the 7-day Zillertal South Tyrol Tour and the 5-day Olperer Rundweg. With optional excursions to climb neighbouring peaks, some of which call for mountaineering skills and glacier crossings.weiterlesen
