If you’re traveling with your family, there’s another reason to visit Mariánské Lázně in summer – the local Miniature Park Boheminium, the fourth largest of its kind in Europe, features over 80 Czech monuments and landmarks built at a 1:25 scale. No kids? The park, which is home to mini versions of Karlštejn Castle, Ještěd Tower, and the Český Krumlov Château, it’s just as fun for adults to visit.
