Tourism has largely focused on Prague, with its great museums, galleries, concerts and other attractions. Many day trips are possible from Prague, including the great western spa town of Karlovy Vary and Mariánské Lázne, early settlements like Kutná Hora and castles like Karlštejn. However, the rest of the country has much to offer the independent traveller with 11 UNESCO World Heritage Sites including Český Krumlov, Litomyšl Castle and the Pilgrimage Church of St John of Nepomuk at Zelená Hora. In addition the Czech Republic boasts an immense number of fascinating castles, churches and other architectural gems. Among the most beautiful areas are the river valleys of the Vltava (Moldau) and Labe (Elbe), the hilly landscape and rocky mountains. The Šumava Mountains of south Bohemia offer excellent rambles and a range of sports, and well-preserved medieval towns like Český Krumlov. Bohemia is also a popular skiing and winter sports destination. In the northeast, the Bohemian Paradise (Český Ráj) is perfect for hiking and climbing amidst unusual scenery. The eastern half of the country, the rich agricultural area of Moravia, offers a variety of wooded highlands, vineyards, folk art and castles. Here life moves at an even more relaxed pace; Brno provides an excellent base for exploring important historic towns like Olomouc, Kromeríz and Telc.
