Hello,
Thank you for the request.
The Junior Card is an offer that you can only buy at railroad stations in Switzerland, the nearest station is in Brig. The Junior Card is an offer that is loaded onto a Swisspass card, which is then sent by post to a residential address in Switzerland.
As you are coming to Switzerland as a tourist, I recommend a Children’s Day Pass or a Half-Fare travelcard.
You can find more information about offers for children here: https://sbb-tickets.cc/en/travel-information/individual-needs/travelling-with-children/tickets-travelcards.html
Have a great day,
Stéphanie
