Znojmo is one of the oldest cities in the Czech Republic and is home to 36,000 inhabitants. On a good day, the town hall tower offers a mesmerizing view of the snowy peaks of the Alps. The city´s adrenalin inducing subterranean tunnel complex is 27 km long and divided over 4 levels. The icing on the cake is Znojmo beer and a visit to the Beer Brewing Museum. If you´re visiting Znojmo during the main tourist season, you can also hop onto the tourist train.
