Take a whole summer off in the mountains, enjoying nature and freedom without any rush. This is a dream for every ambitious hiker, and for those particularly ambitious ones, a very special challenge awaits: to hike across the Alps, but lengthwise! In 70 days from Vienna to the Upper Italian Lakes, from hut to hut, from peak to peak, from one scenic highlight to the next. The long-distance hiking route, designed by the author himself, is presented for the first time in the Rother hiking guide "Vienna - Lago Maggiore." This superlative tour spans an impressive 1300 kilometers, with 70,000 challenging elevation meters to conquer, traversing four Alpine countries - Austria, Slovenia, Italy, and Switzerland - crossing nearly 20 mountain ranges, both well-known and lesser-known.
