The ZTM (Trolleybus/Tram) and ZKM (Bus) networks can also zip you around the relevant cities. Tickets are issued by Gdańsk and Gdynia. Gdańsk tickets allow you to travel in Gdańsk (and Sopot) and Gdynia tickets allow you to travel in Gdynia (and Sopot). If buying a ticket in Sopot you will need to buy a ticket for the direction you are heading i.e. Gdańsk or Gdynia. As of June 1st, 2022, ticket prices are as follows:

• Single tickets cost 4.80zł (reduced 2.40zł)
• 75-minute Night and Fast-line tickets cost 4.80zł (reduced 2.40zł)

As mentioned previously, a recommended way to avoid having to decide on which ticket and then having to negotiate how to get it with the woman in the kiosk is to pick up a Gdańsk/Sopot/Gdynia Plus Tourist Card. In addition to discounts and free entry to many of the sights that the card brings, you will also be entitled to free travel on the whole Tri-city transport network! Pick it up at the tourist information points around the city or at visitgdansk.com.
