We recommend:

  • Good footwear
  • Hiking poles (optional)
  • Clothing suitable for the weather (always carry a waterproof)
Along the hiking trail on the right is certainly the impressive rockslide from 1991.
  • Plan every mountain tour carefully and adapt to participants’ fitness level as well as the weather and season.
  • Weather conditions can change quickly in the mountains. Appropriate clothing is therefore essential, along with adequate supplies of food and water. In uncertain weather, turn back in good time.
  • Inform others of planned route, and whenever possible avoid going alone.
  • Do not leave the marked routes; do not venture onto glaciers without a mountain guide.
  • Please be considerate to other walkers and to plants and animals.
  • Take note of the warning signs drawing attention to the constant danger in river beds and along watercourses below dams and reservoirs.
  • Beware: railway crossing
