Hrad Divci Kamen (also known as Maiden Stone) was a mighty castle back in the 14-16th centuries, but now lays in ruins. These ruins are a short 20 minute drive north of Cesky Krumlov and are well worth a day trip out to explore.
Český Krumlov is famous for its UNESCO World Heritage listed Old Town, which remains in pristine condition after being left unharmed through the two World Wars. There is so much culture and history here; they have an amazing castle, a charming town square and great museums. But is it a good place to bring kids? We had a great time in Cesky Krumlov with our children, aged 2 & 4, by finding a good balance of activities that everyone could enjoy.
