The most common way of evaluating via ferrata routes according to their difficulty grade is using letters. The easiest level of difficulty corresponds to the letter A ("not very difficult"), while the highest level of difficulty is labeled E ("extremely difficult"). The via ferratas in Ötztal are mainly of medium difficulty and appeal to beginners and experts alike. Because the level of difficulty alone is not decisive, the length of a via ferrata should also play a role when choosing a tour. A long but easy climb can be more challenging than a short and crisp but moderately difficult climb. Be sure to find out about the access terrain and available (emergency) exits along the via ferrata.
