What public transport exists from Zurich Airport to Intelaken and for return to Zurich on the same day?

Information on flight and trains between these places.

I would take the train. We had fun and enjoyed good scenery.

Swiss train travel is famously excellent. Plan your trip from Zurich Airport (Z眉rich Flughafen) to Interlaken (Ost or West Station? - it's good to know in advance) with the Swiss Rail search engine: http://www.sbb.ch/en/

On the return trip, you'll want to select Z眉rich HB, the main train station if you're going to stay in the city.

There are excellent tips in the Switzerland travelogues on our non-commercial web site, TheTravelzine: http://www.thetravelzine.com/

If flying is your preference, you can check the Swiss Airline site: http://www.swiss.com

The best way is to take the train. It's convenient and it's fast. It takes about 2 to 3 hours in one way trip. You can buy the ticket in Zurich Train Station.

I agree. Train is the best solution. It takes around 2 hours 20 minutes from Z眉rich Airport to Interlaken. On http://www.sbb.ch/en you can also book your tickets on line and print them on your personal printer. This is the best way to avoid queuing or trying to find out how the ticket machines work at the train stations!
