Prague's sights cluster tightly. The Castle on the hill, the Charles Bridge spanning the Vltava, and the Old Town Square make the classic walk; any two-day visit revolves around them. Beyond the obvious, Prague rewards wandering: the Jewish Quarter of Josefov, the Art Nouveau details of Nové Město, the baroque gardens of Vyšehrad, and the sprawling Strahov and Břevnov monasteries on the western hills.
