Krapina-Zagorje (Croatian: Krapinsko-zagorska županija) is a county in northern Croatia. It encompasses most of the historic region called Hrvatsko Zagorje (Croatian Zagorje). The Krapina-Zagorje county is a candidate for being the most idyllic county in Croatia: the many villages and small towns spread out across the hillsides are perfect for agriculture (vineyards in particular) and summer houses. Although beautiful, the many hills rivers, creeks and lakes through many valleys cause a peculiar effect throughout Zagorje: 15% of the year, fog significantly lowers visibility in the area.
