Located on the Baltic Sea, this eastern European country is the perfect mix of big, lively cities and rural, remote nature. Warsaw, the capital is a bustling modern city where you can find the Palac Kultury I Nauki (Palace of Culture and Science), the Warsaw Uprising Museum, and the Monument of the Warsaw Mermaid. On the other hand, Kraków boasts medieval architecture and Cloth Hall, a Renaissance trading post in the main market square. Poland is a great place to both explore castle ruins and go hiking or kayaking in the northeast region. see moresee less
