Swiss Family Card
The Swiss Family Card is one of the best deals in Switzerland. First of all it’s free. You can request one with any other Swiss rail pass. It allows any children 15 and younger to travel with their parents for free anywhere in Switzerland. This is good on point-to-point travel, on city busses, lake boats, mountain top cable cars, even to Jungfraujoch. For any families traveling to Switzerland with kids, you need to get a rail pass and get a Family Card.
There are still a few trains that require seat reservations – the Glacier Express, Bernina Express and Chocolate trains are the main ones. On these trains you need two things, your ticket (or rail pass) and your seat reservations. Children with a Family Card won’t need a ticket, but you will still need to buy seat reservations in advance for these trips. And like with the Half Fare Cards, not quite every mountain top train or cable car gives free travel. There are always a few exceptions, but they are few and far between. They have to be your own kids (not a niece or grandchild or a family friend), and they need to be younger than 16 at the time of travel (16 year olds are charged the same as adults), but the Family Card is an exceptional deal that is definitely worthwhile for families.
