The city closest to Jungfraujoch is Interlaken, which serves as the primary basecamp and "gateway" to the Bernese Oberland region. However, if you are looking for the absolute closest towns (which are much smaller), Grindelwald and Lauterbrunnen are situated directly at the foot of the mountains and are only a 15–25 minute train or cable car ride from the intermediate stations. Interlaken is roughly 20 kilometers away from the base of the mountain and offers the most extensive hotel and dining options. From Interlaken Ost station, you can reach the "Top of Europe" (Jungfraujoch) in about 90 minutes via the Bernese Oberland Railway. While larger cities like Bern and Zurich are reachable as day trips (about 1 to 2 hours away), Interlaken is the urban hub most intimately connected to the Jungfrau massif. For the fastest ascent in 2026, most travelers stay in Grindelwald to utilize the "Eiger Express" tricable gondola, which cuts the travel time significantly.
