The Eiger 3970m and its north face fascinate mountaineers as well as trail runners. In 2012, passionate outdoor athletes launched the running event "Eiger Ultra Trail." From the very first edition, the starting places were completely sold out. Meanwhile, the E101 route is marked and can be explored on your own.

Thanks to its central location in Europe, Switzerland is served by international trains from over 12 countries. Within Switzerland, Intercity trains run directly from Basel and Lucerne to the Jungfrau Region. Travelers from Zurich change trains in Bern. Trains run every half hour.
Grindelwald
From Interlaken Ost station, we reach Grindelwald without changing trains via the Bernese Oberland Railway (BOB). Important: board the rear part of the train as it splits in Zweilütschinen. Those boarding at the front will end up in Lauterbrunnen. The journey takes 30 minutes to Grindelwald Terminal (V-Bahn). Three minutes later, we arrive at the terminal station in the village.
Grindelwald has three stations (Terminal, Grund, and Dorf). The terminal station (Dorf) is located in the center of Grindelwald.
Wengen
From Interlaken Ost station, we reach Wengen in 44 minutes. With the blue-yellow train of the Bernese Oberland Railway (BOB), we travel to Lauterbrunnen. Important: we sit in the front part of the train as it splits in Zweilütschinen. Those sitting at the rear make a detour to Grindelwald. In Lauterbrunnen, we change to the yellow-green train of the Wengernalp Railway (WAB). This brings us to Wengen in 12 minutes.
Directions
The fastest way to the Jungfrau Region from Basel and Geneva 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 Grimsel or Susten Pass. Both passes are only open in summer. Alternatively, the Simplon Pass with subsequent car shuttle through the Lötschberg tunnel is an option.
Grindelwald
From Interlaken, we follow the main road to Zweilütschinen. Here we turn left towards Grindelwald. The entire drive takes about 30 minutes and leads along a partly winding route.
Wengen
Wengen is car-free. If we arrive by car, we must leave it in Lauterbrunnen and take the train. The journey from Interlaken to Lauterbrunnen takes about 20 minutes.
Parking
Grindelwald
There are three public parking garages: Eiger+ Parking Garage (252 spaces), Sports Center Parking Garage (160 spaces), and the new Terminal Parking (1000 spaces) of the V-Bahn. Alternatively, we can use the parking lot in Grindelwald Grund.
Wengen
Directly below Lauterbrunnen station is a multi-story parking garage. Alternatively, the parking lot at the Lauterbrunnen church can be used. From here, a bus runs every half hour to the station. It takes about 10 minutes on foot.
A covered passage leads from the Lauterbrunnen parking garage to the trains to Wengen.
