Extreme via ferrata routes are currently very popular, and a classic is now presented in a new format. While the first edition featured C-grade routes, the revised edition only includes a few long D-routes. The focus is on E-grade via ferratas, extending even to F/G. In addition to an information block and the colorful climbing topos familiar from many via ferrata signs, the extreme routes are beautifully visualized through numerous images. This work is a mix of a guidebook and a small picture book, geographically extending to Lake Geneva. It is a resource for via ferrata enthusiasts who want to know where the steel cables are steepest and the challenges in this popular sport are greatest.
