Having arranged a time in advance, get picked-up from your hotel by your private guide and embark on your 4-hour walking tour. Head for the nearest tram (own expense) and travel to the top of Castle Hill. Walk through the historical Hradcany area toward Prague Castle, passing through all of its three courtyards, and pausing along the way to take in the scenery and hear your guide provide details on the history of the famed castle. Make time to admire the Gothic St. Vitus Cathedral, site of many coronations.
Make your way down Castle Hill and through the streets of Mala Strana, or 'Lesser Town,' crossing the Vltava river by Charles Bridge to get to Prague's Old Town. Head for Josefov, the Jewish quarter, and visit the Old New Synagogue, the longest still-functioning synagogue in Central Europe, and the Old Jewish Cemetery. Get a more contemporary view of Prague by admiring the 'Dancing Building,' designed by Frank Gehry. Walk through Wenceslas Square and learn about the many significant events that took place there, including the demonstrations of the Velvet Revolution in 1989.
Finish your tour with a view of the Astronomical Clock in Old Town Square. Choose to say goodby there or allow your guide to drop you off back at your hotel.
