Interlaken Ost vs Interlaken West — which station tourists actually need

Which Interlaken station do you need? Interlaken Ost connects to the Jungfrau valleys, Harder Kulm and Lake Brienz. Interlaken West sits by Lake Thun and the line toward Spiez, Thun and Bern.

Interlaken has two proper SBB stations — Interlaken Ost and Interlaken West. There is no “Interlaken Central.” Your next ride decides which one matters.

Ost is the gateway to the Jungfrau Region: the Berner Oberland Bahn toward Grindelwald and Lauterbrunnen starts here. The Harderbahn valley station is a short walk across the Aare; Lake Brienz boats leave nearby. The Luzern–Interlaken Express is framed with Ost as its Interlaken end.

West sits by the Lake Thun boat landing and on the corridor toward Spiez, Thun and Bern. If your day is a Thun lake cruise or onward toward Bern, West is often the simpler stop. Many long-distance trains serve both — check your ticket and the SBB app for the exact station name.

Choose Interlaken Ost when…

You are heading into the Jungfrau Region on the Berner Oberland Bahn toward Grindelwald or Lauterbrunnen. You want Harder Kulm (Harderbahn valley station is a short walk / across the Aare from Ost; funicular about 10 minutes). You need Lake Brienz boats (landing near Ost) or arrive/leave on the Luzern–Interlaken Express framed with Ost.

Choose Interlaken West when…

Your day is a Lake Thun cruise (port next to West) or you continue toward Spiez, Thun and Bern on that corridor. West is not “the secondary station” — it is simply the better door for Thun-side plans.

Practical tip

Many InterCity and regional services call at both. Always read the exact station name on your ticket and in the SBB app. Walking between Ost and West is possible along the Aare, but with luggage or tight connections, pick the station that matches your onward ride.

Ticket rules and prices can change — confirm on official pages before you travel.

Is Swiss Travel Pass enough for Harder Kulm?

MySwitzerland STP benefits name free mountains Rigi, Stanserhorn, Stoos only, plus up to 50% on many other mountain excursions. Harder is not named on that free list — do not assume free travel. Check the STS area of validity map and jungfrau.ch tickets.
