Poland
This is a small town on the banks of the Vistula river, about 100 km south of Warsaw. It is an architectural gem, a Renaissance town with ruins of a medieval castle. It is surrounded by beautiful unspoilt countryside with very unusual deep ravines - great for walkers. There are lots of nice bars and resturants and a terrific tea room called Herbaciarnia u Dziwisza.
100 km south of Warsaw, easy to drive to, nearest station Pulawy Miasto and from there by taxi for about £10
