The train ride between Interlaken Ost to Zermatt takes 2h20.
In all cases, you will need to change trains twice, in Spiez and Visp. The transfer times are typically 5- 10 mins and trains can be busy. So you should familiarize yourself with the track numbers before you arrive and move with purpose.
💡On weekends, these trains can be very busy, particularly between 16:00 - 19:00 when people are traveling to and from their weekend getaways. When checking the schedule on SBB.ch, look for the red people icon next to the train connection. This indicates that they expect the train to be very busy.

Optional seat reservations
I don't recommend reserving seats for this journey.
First, it's not possible to make seat reservations for the Visp-Zermatt train.
Second, although you can make reservations on the other two trains, the journeys are relatively short, so it feels a little unnecessary.
But if it's very important that your group sits together, you can make a seat reservation for trains on this journey that allow it (look for the R symbol on the timetable). You can do this online a couple days before your trip. Make seat reservations here.
Where to sit
It's not super important which side of the train you sit on during this ride, particularly since you have to change train twice. But here are a few tips, direction Interlaken to Zermatt.
Interlaken - Spiez: Sit on the right side, which faces the lake.
Spiez - Visp: Most of the journey is in a tunnel, so it doesn't matter.
Visp - Zermatt: Both sides are fine, but I slightly prefer the left side of the train.
When to ride
This train ride is easy to include in your itinerary, simply as your transfer from Interlaken to Zermatt.
If you ride in the morning, you could arrive in Zermatt by 10 or 11am, with plenty of time for an afternoon in the mountains. In this case, we would suggest the Gornergrat for the afternoon since it closes later than other mountain transport.
If you ride in the evening, I suggest leaving around 18:00 on weekdays to avoid the worse of the business commute hours.
