This hike, classified as difficult, crosses a variety of alpine landscapes. The trail initially follows the cascading Bisbach river before climbing steeper slopes into rocky terrain where hikers may need to use their hands at times. The path finally leads up slopes of scree to reach the Gross Kastel summit plateau, which rewards walkers with beautiful views.

  • Summit cross
  • View of Täsch, Randa, Matter valley
  • Impressive view of nearby Weisshorn

We recommend:

  • 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.
  • It is forbidden to walk on the ski pistes.
  • 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
