The Zürich Card is a guest card that offers free travel in the city of Zurich and its sourroundings. But, the Zurich Card is not free of charge, it is a payable offer.

With this post, however, I would like to emphasise on the fact that the Zürich Card is not valid to travel to Lucerne. If you are caught with this ticket on a train to Lucerne, you are expected to purchase a new ticket with a surcharge.
- Using the IR 75 train, the ticket is valid as far as Thalwil.
- On IR70 trains, the ticket is not valid at all.
Please let us know should you have further queries on the use of the Zurich Card.
Kind regards,
Roland
