To reach the mountain summit of Grindelwald First from Interlaken in 2026, you must take a two-stage journey involving a train and a gondola. First, board the Bernese Oberland Railway (BOB) at the Interlaken Ost station. Ensure you sit in the correct section of the train, as it often splits at Zweilütschinen; look for the carriages marked for "Grindelwald." The train ride takes approximately 30 minutes, winding through spectacular alpine scenery. Once you arrive at the Grindelwald station, it is a pleasant 10-to-15 minute walk through the charming village center to the "Firstbahn" valley station. There, you board a 6-person aerial gondola for a 25-minute ascent to the "First" summit station at 2,168 meters. This route is exceptionally efficient and runs every 30 minutes. In 2026, it remains the most popular way to access the First Cliff Walk, the First Flyer zipline, and the legendary hike to Lake Bachalpsee, offering one of the most accessible "High Alps" experiences in Switzerland.
