The sun's rays are particularly intense in the mountains. Sun cream with a high protection factor, a sun hat and sunglasses with UV protection should therefore be part of your luggage.

Even in summer and in good "starting weather", warm clothing and rain protection are part of the equipment. The onion principle with several layers of clothing is recommended.

  • Day hiking backpack with rain cover
  • Sturdy and comfortable shoes
  • Clothing adapted to the weather and hard-wearing (onion principle)
  • Charged mobile phone
  • Pocket pharmacy
  • Beverages and food
  • Pocket knife equipment

Safety Guidelines

  • Regularly check the location and compare it with the schedule. In this way, alternatives, shortcuts, demolition, etc. can be considered in good time.
  • In the event of bad weather, turn back in good time or seek shelter. If thunderclouds are gathering, it is advisable to abort the tour as soon as possible.
  • Do not leave the marked paths. Stay on the official hiking trails even if trails look like shortcuts. Some of these paths are not maintained and can end in a dead end.
  • Lost? Stay together as a group and return to the last known point. Wait for better visibility or call for help.
  • Plan enough time and energy reserves for the descent.
  • Slow down and take breaks.
  • Steep grass, scree and snow slopes are safer to tackle on the ascent than on the descent.
  • For the descent, choose the easier option or take the train down to the valley.
  • Avoid herds of cattle calmly and at a sufficient distance. Keep dogs on a leash.
  • In encounters with guard dogs, the following applies: Remain calm so that the dog realises that you are not a danger to the herd. Keep a generous distance from the herd.
  • Allow mountain bikers to pass without obstructing their ride unnecessarily.

Getting There

Public transport

Thanks to its central location in Europe, Switzerland is served by international trains from over 12 countries. Within Switzerland, Intercity trains run from Basel and Lucerne directly to the Jungfrau Region. Travellers from Zurich change trains in Bern. The trains run every half hour.

From Interlaken Ost railway station we reach Grindelwald without changing trains on the Bernese Oberland Bahn (BOB). Important: Get on the rear part of the train, as it splits in Zweilütschinen. If you get on at the front, you will end up in Lauterbrunnen. The journey takes 30 minutes to Grindelwald Terminal (V-Bahn). Three minutes later we are at the terminal in the village.

There are three stations in Grindelwald (Terminal, Grund and Dorf). The terminal station (Dorf) is in the centre of Grindelwald. From Grindelwald train station, bus line 121 runs every half hour to the Upper Grindelwald Glacier.

Getting there

From Basel and Geneva, the fastest route to the Jungfrau Region is via Bern. From Zurich, the route via Lucerne and the Brünig Pass is recommended. The pass is open all year round.

From the south, travel to the Jungfrau Region via the Grimsel or Susten Pass. Both passes are only open in summer. An alternative is the Simplon Pass with subsequent car transport through the Lötschberg tunnel.

From Interlaken we follow the main road to Zweilütschinen. Here we turn left towards Grindelwald. The whole trip takes about 30 minutes and leads over a partly winding road. The Upper Grindelwald Glacier can be reached by continuing on the main road to the Hotel Wetterhorn / signposted Upper Grindelwald Glacier.

Arrival Grindelwald


There is a public car park at the Upper Grindelwald Glacier / Hotel Wetterhorn.
