The ZTM operates Gdansk’s local transport system, which consists of tram and bus lines. Tickets can be bought from the drivers or in vending machines and the fares are either based upon number of journeys or travel time so you have to estimate how long your trip will take before buying a ticket. If you’re planning a busy day of sightseeing in the city, splurge on a day travel ticket (valid on all trams, buses and night buses for 24 hours). Don’t forget to validate your ticket by sticking it in one of the orange or brown boxes located all around the stations or on the bus or tram. Commuter rail SKM is a good way to travel between Gdansk, Gdynia and Sopot. Trains leave from Gdansk’s main train station, Gdansk Glowny.
