However long you plan to stay in Poland, you should ensure you find time to visit the impressive Malbork Castle in the far north of the country.
As the castle is a very popular attraction it is open throughout the year, although it is best to avoid mid-summer if possible due to the large crowds.
Also nearby is the Slowinski National Park which offers miles of walking trails and beautiful beaches.
Construction of the castle began way back in the 13th century and it remains the largest brick building in Europe and the largest castle by area in the whole world.
A visit to the castle can be combined with a stay in the nearby city of Gdansk which has many historical buildings, museums and other attractions to explore.
