About Gdansk

May-September is the sweet spot: stroll Długi Targ, climb St Mary's, and ferry to Westerplatte. Sea breezes keep harbour walks comfortable on warmer days.

Travel Tips

Dlugi Targ Before Ships
Long Market and the waterfront fill when Baltic cruise tenders arrive. Walk Motława quays at opening, then visit St Mary’s or the Crane before midday queues.
Trams to Sopot & Gdynia
SKM trains link Gdańsk, Sopot and Gdynia as one metro-like corridor. Within Gdańsk, trams reach the airport and outer beaches faster than taxis in summer traffic.
Museum of WW2 Tickets
The Museum of the Second World War and European Solidarity Centre need substantial time; buy tickets online for weekends. Church climbs like St Mary’s charge separate tower fees.
Baltic Wind & Amber Streets
Harbour winds cut through even mild days - bring a shell layer. Amber stalls are part of the tourist strip; compare prices and ask about certifications before large purchases.
