Prague has one of the best public transportation systems in Europe. The metro, trams and buses are used by two-thirds of Prague’s population and cover the majority of the city and outskirts. Especially the metro makes getting around town a breeze since it enables you to cover long distances in a matter of minutes. If you can’t continue to your destination on foot, you’ll be able to catch a tram or bus from near the subway station.
