In Gothenburg, public transport is easily accessible and reliable. Västtrafik operates the public transportation and they run the buses, trams and ferries.
When travelling in Gothenburg, you can use the same ticket for trams, buses and ferries. You can buy your ticket at any Västtrafik’s sales outlets as well as kiosks like Pressbyrån and 7-Eleven or the grocery stores. You can also buy your ticket with cash or card on board (this do not apply every transport). On the trams, you can buy your ticket on board with coins or card from the ticket machine and on the boats (southern archipelago boats), just pay your ticket with cash or card to the staff on board. If you take the river boats, you can buy your ticket from the staff on board but they only accept cards. However, on the city buses you cannot buy tickets on board, so make sure you have bought a ticket before boarding.
If you have a smart phone, you can download for free Västtrafik To Go app, which is an easy way to buy single, period and day tickets. (Available for Android and iPhone)
Gothenburg is a bicycle friendly city, with good bicycle paths, so why not do as many locals do, go by bike.
