Hello Kate_28
Your travel plans are what it all depends on. It is advisable to first plan your trips, and as the last step of the planning process, to consider the tickets or travel passes. If you plan to take a few mountain trips, the Swiss Half Fare Card is indispensable for adults, it saves you a lot of money.
The Saver Day Pass is certainly an option, but sometimes a conventional point-to-point ticket would do as well.

For individuals who are 15 years of age, it is possible to purchase the Children Day Pass, provided that the trip is for a single day. If you are embarking on multiple journeys, it is advisable to buy the Junior-Card from the SBB Travel Center. If you purchase the Swiss Half Fare Card for adults, then the Swiss Family Card is offered complimentary. This entitles your 15-year-old to travel free of charge when accompanied by you. The 16 years old equals the adult, there is no special discount. The Tandem ticket is not available to you.

Alternatively, you can buy the Swiss Travel Passes for the adults, and Swiss Travel Pass Youth for your 16 years old. Again, the complimentary Swiss Family Card entitles the 15 years old to travel free of charge when travelling with you. The Swiss Family Card is only offered when buying the Swiss Half Fare Card or a Swiss Travel Pass or Swiss Travel Pass Flex.
