Can I buy swiss pass at Zurich rail station?

Hi nanatpeg,

You can find all purchase option at the Swiss Pass page. If you wait until Zurich to buy the pass, you have to pay the full fare between the border and Zurich. Theoretically you can get out at a staffed border station and buy the pass there, but then you miss your train and have to wait for the next one. It's easier to buy online to not loose time and get free traveling right from the border. In case of Thailand you can get the pass here and pay in your own currency. Don't forget to check out the promo codes.

Here's a list of hotels near the Zurich rail station, in case you haven't booked yet.

Enjoy your stay!
