Reaching the office

In Geneva, when staying in a hotel, you are provided with a complimentary public transport pass. This pass will allow you to use all public transports (train, tram, bus, even the yellow boats on the lake) within the extensive Geneva area (zone 10) for the entire duration of your stay, including your departure day. So do not throw it away because it will allow you to reach the airport or the train station.

Coming from the airport:

In the baggage hall of Geneva airport there are machines that will give you a complimentary public transport ticket, that you can use on all public transport in Geneva (as above), for 80 minutes.

Coming from the Cornavin train station:

If you need a public transport ticket, you can purchase it from the machines or using the TPG app.
