On Friday March 28, my friend and I will be traveling from Geneva Airport to Interlaken West train station, just the one way trip. We are meeting up with my dad and we are leaving by car a few days later.
We are trying to find the cheapest train travel option from the Geneva Airport to Interlaken West. I understand that we will have to switch at Bern. I would like to find a scenic train, and we don't mind if it takes a little longer, because I know that slower trains are often cheaper.
Should we buy tickets now online, or wait and simply buy them the day of? Also, what route would you recommend? Any help would be greatly appreciated!
