Hourly IR Geneva–Brig trains give you a direct Valais spine
From GVA’s rail station under T1, you ride SBB’s InterRegio (IR) Geneva–Brig line straight toward Valais in about 2 h 40–3 h, depending on the run. Some IRs start right at Genève-Aéroport; others start at Genève-Cornavin, 7 minutes away by the airport shuttle train that runs every 10–20 minutes. Check the SBB app for “IR Brig” specifically so you know if you’re boarding at the airport or changing at Cornavin.
Expect about hourly IR departures on this route, with the standard second‑class full fare Geneva–Brig landing around CHF 60–70 one way before any Half Fare Card or Supersaver discounts. The line runs via Geneva, Nyon, Lausanne, Montreux, then into the Rhône valley with stops like Sion, Sierre/Siders, and Visp before Brig. If you’re heading to Montreux, Sion, Sierre, or Brig itself and don’t care about saving 10–15 minutes, this is the straightforward option.
Seat reservations on IR trains are optional and almost nobody bothers with them; most coaches are free seating in both 1st and 2nd class, with a few marked reservation rows. Regulars say they board front or rear cars to dodge tour groups that pack into the middle coaches. On winter Saturdays, skiers with gear can fill entire cars between Geneva and Sion, so luggage racks and door areas get tight.
The scenery pays off: Reddit rail fans call this the “classic route into Valais” thanks to the run along Lake Geneva between Geneva and Montreux, then the Rhône valley views after Lausanne. For the lake section, sit on the right side leaving Genève-Aéroport; after Montreux and into Valais, people often swap to the other side for long valley vistas toward Sion and Brig. The full lake‑plus‑valley stretch lasts well over 90 minutes.
Onboard catering on IR is limited compared with IC: some sets have just vending machines, others only a small trolley, and you can easily get nothing if it’s busy. Many locals grab food at Genève-Aéroport station or at Lausanne, where you’ll usually have 3–10 minutes if changing. With reported IR delays in winter around Lausanne and the long Geneva–Brig run, buy snacks and water before boarding and treat any trolley as a bonus, not a plan.
Step-by-step from GVA to Brig or Valais towns
- 1. From the arrivals level at T1, follow signs to “Gare CFF” and walk 3–5 minutes into Genève-Aéroport station.
- 2. Use the SBB app or ticket machines to buy a Geneva–Brig ticket (2nd class full fare around CHF 60–70) or to intermediate stops like Montreux, Sion, or Visp.
- 3. Check if your IR to Brig starts at “Genève-Aéroport” or “Genève” (Cornavin); if it’s Cornavin, board any airport–Cornavin shuttle (7 minutes) and change there.
- 4. Once your IR arrives, walk to the front or rear coaches, stash big bags in the racks near the doors, and grab a right‑side window seat for the lake section.
- 5. Stay on the same IR until your stop: about 1 h to Montreux, roughly 1 h 50 to Sion, about 2 h to Visp, and around 2 h 40–3 h to Brig.
Practical tip: On winter weekends, aim for an IR that doesn’t line up exactly with big ski‑resort check‑in times, or you may be standing from Geneva to Lausanne.
