Scenic train routes - sit on left or right side?

Hello,

These are the train routes that I will be taking in two weeks. I know some are scenic and some aren't. Can someone please let me know which side of the train I should sit?

- Zurich Flughafen - Luzern - Brienz

- Brienz - Interlaken Ost - Thun

- Thun - Visp - Zermatt

- Zermatt -Visp - Spiez - Wimmis

- Wimmis - Bern - Olten - Luzern

- Wimmis - Spiez - Interlaken Ost - Luzern

- Luzern - Zurich Flughafen

Thank you!

Hi chachacha,

• Luzern-Brienz-Interlaken Ost is part of the Golden Pass route. Preferred sides are mentioned at our Golden Pass page;
• Thun-Visp: left side, for views of Lake Thun. Visp-Zermatt is part of the Glacier Express route. Preferred sides for this leg are mentioned here;
• I don't have strong preferences for your remaining routes. Views are often fine from both sides, and trains regularly switch valley sides.
