From Interlaken Ost railway station, you can reach Grindelwald without changing trains by taking the Bernese Oberland Railways (BOB) train. Important: you need to board at the back of the train because it splits at Zweilütschinen.

To reach Grindelwald, you must depart from the Interlaken Ost (East) station. While Interlaken has two main stations, Interlaken West and Interlaken Ost, only Interlaken Ost serves as the gateway to the Jungfrau region valleys. From here, you board the blue and yellow Berner Oberland-Bahnen (BOB) trains. A critical "pro-tip" for 2026 travelers is that the train often splits at Zweilütschinen; ensure you are sitting in the specific sector of the train marked for Grindelwald (usually the rear half), while the front half continues to Lauterbrunnen. The journey takes approximately 35 minutes and runs hourly. If you accidentally end up at Interlaken West, you can take a quick 5-minute local train or bus to Interlaken Ost to catch your connection. The ride is fully covered by the Swiss Travel Pass, making it a seamless part of a classic 2026 Alpine itinerary.
