Almost a dozen long-distance trails crisscross Europe, most of which are several thousand kilometers long. They can be tackled in individual stages. The most popular long-distance trail is the E5, which starts on the French Atlantic coast and stretches through the German-Austrian-Italian Alps to Verona. In some parts, not only endurance is required, but also alpine knowledge and a head for heights, as the path winds over peaks exceeding 3000 meters in elevation. It is advisable to entrust oneself to a mountain guide for these more challenging sections.
