Interlaken Public Transport Guide 2026: Passes, Guest Card & Jungfrau Regional Travel
Interlaken is the adventure capital of Switzerland and the primary gateway to the Jungfrau region (Grindelwald, Lauterbrunnen, Wengen, and Jungfraujoch). Whether you are taking local STI buses between Interlaken West and Ost or riding mountain railways, here is everything you need to know about tickets, guest passes, and regional transit in 2026.
1. How Interlaken's Local Public Transport Works (Interlaken Guest Card)
Interlaken has a compact local transit area connecting the two main railway stations — Interlaken West and Interlaken Ost — along with neighboring towns like Wilderswil, Bönigen, and Ringgenberg.
- Free Interlaken Guest Card 🎁: Every guest staying at a hotel, hostel, or vacation rental in Interlaken receives a Guest Card upon check-in. It grants **free unlimited travel** on local STI buses and local train connections within the Interlaken urban zone (Ringgenberg to Wilderswil).
- Traveling from Zurich Airport (ZRH) to Interlaken: Direct SBB trains connect Zurich Airport to Interlaken in approximately 2 hours and 15 minutes (via Bern or Spiez).
2. Regional Travel: Jungfrau Region, Cable Cars & Mountain Trains
While the local Guest Card covers city buses, excursions higher up into the Alps require regional mountain passes or tickets:
- Jungfrau Travel Pass / Berner Oberland Pass: Ideal for travelers spending 3+ days exploring Grindelwald, Lauterbrunnen, Mürren, and Lake Thun/Brienz boats.
- Swiss Travel Pass: Covers 100% of trains to Interlaken, Grindelwald, and Lauterbrunnen, plus discounts (25% to 50%) on high-mountain cable cars and the Jungfraujoch cogwheel railway.
- Lake Thun & Lake Brienz Passenger Ferries: BLS navigation operates scenic boat cruises departing right from Interlaken Ost and West quays.
Navigating mountain train transfers in the Jungfrau region requires constant access to the SBB Mobile App, live weather webcams (for peak visibility before buying expensive summit tickets), and digital pass validation.
One Pocket WiFi for Everyone: Renting a single 5G pocket Wi-Fi router at Zurich Airport allows up to 10 smartphones, tablets, and laptops in your group to enjoy unlimited high-speed data without expensive individual roaming fees.

Interlaken is a global hotspot for digital nomads and business travelers combining remote work with outdoor adventure.
Working while commuting on alpine trains? Free SBB Wi-Fi is limited to major station platforms and does not function on moving mountain trains or remote hiking routes. A personal 5G pocket router delivers secure, high-speed connection for Zoom calls and VPNs from alpine meadows to lakeside cafes.
Ticket controllers strictly inspect all passengers on local buses, SBB trains, and BOB mountain railways. Traveling past the local Interlaken Guest Card zone without a valid extension ticket or active pass leads to a mandatory 100 CHF fine plus ticket fare.
