Here is a handy resource to use for when you want to venture outside of Prague. I like how this
Discover Czech page lists distances between cities, so you
can plan day trips or excursions beyond Prague. It also suggests minimum lengths of stay for visiting places like
Cesky
Kromlov, Kunta Hora or
Ceske Budejovice. There are, of course, tons of
online recources to help with trip planning to Prague or
other parts of the Czech Republic. These tools make it quite easy to plan things by yourself, or you can consider a
tour like Intrepid Travel’s Bohemian Adventure, which
visits Prague, Cesky Kromlov and southern Moravia.
