Two groups of Czech tourists were rescued by helicopters in the Austrian Alps over the weekend. In the other, a Czech family needed help on a via ferrata on the Grosser Donnerkogel mountain. When they realised the ferrata was too difficult for them, they decided to descend to the valley via an unmarked trail. The second group, a family, took a wrong turn while descending from the summit of Grosser Donnerkogel. All the tourists were safely taken down to the valley.
