Train, bus 210, Uber/Bolt or taxi all work. The best option changes with where you are staying, how much luggage you have and whether a child is already asleep.
The airport railway station is directly in front of the terminal and is connected to it by a covered footbridge.
Take the airport train to Gdańsk Wrzeszcz, then change to SKM for Gdańsk Główny or Gdańsk Śródmieście. The airport specifically notes that the centre journey requires this transfer; at Wrzeszcz, the onward SKM for the centre leaves from platform 3.
The airport says journeys to Sopot and Gdynia can be direct via Wrzeszcz or may require a change there. Gdynia also has an alternative direct route via Osowa. Check your exact train because the pattern varies.
Line 210 runs every day between the airport and Gdańsk Main Railway Station / city centre. The airport gives an approximate journey time of 40 minutes between the centre and the airport.
Line 110 connects the airport with Gdańsk Wrzeszcz railway station every day. The airport gives a typical journey of about 25–35 minutes. This is useful if your accommodation is in Wrzeszcz or you want to continue by SKM.
Often the easiest answer after a flight — but the child-seat question matters.
Late arrival, two suitcases plus a stroller, a sleeping toddler, accommodation away from a station, or simply wanting door-to-door travel after a difficult flight.
A standard Uber/Bolt/taxi ride does not mean a suitable child seat will automatically be available. The legal rules for taxis also differ from the general private-car rule.
Bus 210 is the simplest public-transport option because it avoids the Wrzeszcz train transfer. Use a car if luggage/tired children make door-to-door worth the extra cost.
Check the train first. Depending on the service it may be direct or need a change at Wrzeszcz; either way it avoids travelling into Gdańsk centre first.
Train first. There are options via Wrzeszcz and an alternative route via Osowa. Use the airport journey planner for the exact arrival time.
The airport's N3 night bus operates roughly between 23:00 and 04:00 and links the airport with Gdańsk Main Station / Wrzeszcz depending on direction. The airport gives about 50 minutes between Gdańsk Main Station and the airport. With very small children, a taxi/rideshare may still be the easier late-night choice.
