I initially thought to ask this in the Switzerland forum but perhaps it is better here in the Transportation forum.
I am writing to verify from Swiss residents and anybody else who can confirm.
Let’s say I want to do a day trip within Switzerland between Basel and Grindelwald.
seat61.com offers a tip that in order to save money, buy from the Deutsche Bahn website 90 days in advance and select Freiburg as the departure and Grindelwald as the destination. The fare is €19.90. Then for the return to Basel, on the DB website enter Freiburg as the destination. Same low fare.
In both directions, Basel is a station in which to change trains. Thus seat61 advises that it is perfectly legitimate to buy tickets from the DB website using Freiburg as a departure origination in the morning and a destination in the evening. I have the DB app and would buy both through the app making the printing of tickets unnecessary.
It all seems too good to be true. Is this in fact true? Is this legitimate?
Thank you.
