Anyone who follows the trail here must be aware that it ends up becoming a real via ferrata. The beginning of the trail is like a beautiful mountain hiking trail. Towards the end, however, you need to be absolutely sure-footed and wear good shoes, especially on the descent, even if it is only a short stretch. The scenery is of course very attractive. 🧗🙂
