A whole range of outings is offered by Prague Sightseeing Tours – look for the yellow kiosk near the metro entrance on náměstí Republiky. The two-hour ‘Informative Prague’ bus tour (adult/child 410/280Kč, departing 11am and 1.30pm from April to October) takes in all of Prague’s important historical sites, and the ‘Grand City’ tour (660/330Kč, departing 9.30am and 2pm April to October) combines a bus tour of the main sites with a walk through Prague Castle.
