First step is to collect audio guides before taking the Gornergrat Bahn cog train to Rotenboden. From here, the trail leads across the Gorner glacier to the Monte Rosa Hut (2,883 m). The hike of about four hours allows plenty of time to listen to nine stories about the climate, each lasting about five minutes.

  • Visitors can also listen to the climate stories on the train ride to the Gornergrat (without doing the hike)
  • Audio guides in German, English and French (deposit: CHF 50)
  • The guides can also be downloaded onto smartphones as a podcast, from
  • The trail is classified as an alpine hiking T4 trail on the SAC scale
  • Crampons required

Rotenboden - Monte Rosa Hut (route across glacier marked with flags)

(Hiking time in reverse direction: approx. 3.5 h)

This hike is marked on the signposts as “Klimahörpfad”.


Note: The old trail will continue to be maintained, so hikers can enjoy a circular route.

We recommend for the Klimahörpfad (climate audio trail):

  • Audio guide (available with deposit from Zermatt Tourism, Gornergrat Bahn station or the Zermatters). Also available as podcast.
  • Good mountain boots
  • Crampons
  • Hiking poles (optional)
  • Clothing suitable for the weather (always carry a waterproof)

Note! The crossings to the glacier and the glacier passages are constantly changing and often very tricky. Good climbing boots and crampons are essential. Sticks or ice axes can be helpful and it's a good idea to take a rope. Good stamina is also important.

The route leads across the glacier. Recommended: book a mountain guide.

Instead of returning from the Monte Rosa hut on the same day, this modern hut has 120 beds for overnight stays.

  • 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.

Important! Difficulty level T4 – the route is difficult. Glacier traverse. Unsuitable for inexperienced mountain hikers. We recommend the services of a mountain guide. Return hiking time 6-7 hours.
