From the airport, the city bus that runs to the main railway station is the simplest option — expect a journey of around forty minutes and a ticket of roughly five zloty, bought from the machine at the stop or in the city transport app. The train is the other route: a suburban service from the airport terminal, a change at Gdansk Wrzeszcz onto the SKM commuter line, and on into the centre, for something like eight or nine zloty in total and a similar three-quarters of an hour. A taxi or ride-hailing car will usually land somewhere in the region of eighty to a hundred and twenty zloty depending on traffic and time of day.
Once you are in, you will barely use transport at all. Gdansk Glowny, the main station, is about a ten-minute walk from the Golden Gate. Everything in the morning and midday plan below sits within roughly fifteen minutes on foot of everything else in it. The only leg that genuinely benefits from a tram is the run north to the shipyard, and even that is walkable in around twenty-five minutes.
The neighbourhood to stay in is the Main Town itself, or Granary Island directly across the water from it — the second gives you the better view back at the gabled facades. Wrzeszcz, a couple of stops out on the SKM, is where prices drop, but on a twenty-four-hour visit the extra journey at midnight is worth paying to avoid.
8:30 — Long Market. Start at the Golden Gate and walk east along Dluga and Dlugi Targ, the ceremonial route Polish kings once processed down. The gabled merchant houses are reconstructions, rebuilt after 1945 from paintings, photographs and surveyors' drawings, and they are extraordinary — not a pastiche, but a deliberate act of recovery. The Neptune Fountain marks the middle. Artus Court, the old merchants' guild hall, stands behind it, and the Main Town Hall rises over the north side with a tower you can climb.
Here is the first thing to skip. You cannot do the Town Hall interior, Artus Court and the St Mary's tower and still have an afternoon left. Choose one. The Town Hall's Red Room is the most heavily decorated of the three; the tower at St Mary's is the better view. Artus Court is the one to drop unless guild halls are a particular interest of yours.
9:30 — St Mary's Church. Guidebooks generally rank it as the largest brick church in the world, and the interior is so cavernous and so pale that it reads as under-furnished, which is roughly the effect the Reformation intended. The astronomical clock in the north transept is worth hunting down. The tower climb is somewhere north of four hundred steps up a narrowing spiral with no lift and no shortcut back down; entry costs a small amount, think in the region of twenty zloty, and the church itself asks a token sum on top. Allow about forty minutes if you climb, and skip it altogether in heavy rain, when the platform gives you cloud.
10:30 — Mariacka Street. The prettiest lane in Gdansk, to our eye: stone terraces stepping down from each doorway, gargoyle waterspouts overhead, and amber in every window. Amber is the local trade and has been for centuries. The workshops on Mariacka are a cut above the stalls out on Dluga, but if you want to understand what you are buying before you buy it, the Amber Museum now occupies the Great Mill, a vast medieval grain building about ten minutes north of the lane. It moved there in 2021, spreads over three floors, has a lift, and covers essentially every kind of fossil resin found anywhere on earth.
If you would rather see amber used than catalogued, St Bridget's Church, just behind St Catherine's on the same short walk, is building an altar out of it — an enormous, still-unfinished work widely described as one of the largest amber structures anywhere. It is usually open from mid-morning to early evening on weekdays and Saturdays, and from early afternoon on Sundays.
