Euro are accepted in Gdansk, but you will get the change in zloty. It’s not quite profitable, so you’d better change currency. In case you don’t have cash, credit cards are accepted at the restaurants and in the shops, whereas cash is needed for street attractions.

The Baltic sea water isn’t as warm as in some other southern seas. In the Gdansk Bay, even in the hottest months (June–September), its temperature is likely to be below 20ºC (68F). Remember that if you are not a fan of cool water. And even if you are, checking seawater temperature online in advance is a good idea.

This 46-meter hill behind the present-day bus and train stations served a military function in the past. You can visit nearby Centrum Hewelianum to walk the brick tunnels of the local 19th-century fortress. However, even if you are not interested in military history, the hill offers a great Gdansk view. The 16-meter Millenium Cross crowns its top.
