A:
Bohemia is still called Bohemia today, but it is a region of the modern nation of the Czech Republic rather than a separate kingdom or country. In the Czech language, Bohemia is called Čechy.

Despite its artistic, alternative connotations, Bohemia is simply a region of the Czech Republic. The historical province has been incorporated into many nations and empires over the centuries, from the Habsburg Empire to post-war Czechoslovakia, and modern-day Bohemia reflects this rich, long history. Bohemia is the westernmost region of the Czech Republic and its largest. Incorporating the Czech capital Prague and the popular towns of Karlovy Vary, Plsn, Cesky Krumlov, Ceske Budejovice, and Kutna Hora, there’s a lot to see and many things to do in Bohemia.
There’s no real need to rent private cars in Bohemia because this part of the Czech Republic has reliable, affordable public transport. Trains connect most major towns and cities–and even some more remote ones, on limited schedules–and long-distance buses are a viable alternative. Prague has an excellent transport system, with a small metro and plentiful buses and tram lines. Small Bohemian cities, such as Ceske Budejovice, are serviced by buses, while smaller towns, like Cesky Krumlov and Kutna Hora, are walkable.
The further you travel from Prague, the harder it is to get by on English alone. While many younger Czechs speak good English, many older folk don’t–although they may understand German, especially nearer the German border. When traveling around Bohemia, especially if you’re relying on public transport, it’s sensible to learn (or look up) the days of the week in Czech so you can read timetables. Learning the names of foods to read menus is also smart–you can’t go wrong with knedliky or smazeny syr washed down with a chilled pivo.
