The main state route no. 6 is the most important cycling route in the Krapina-Zagorje County, leading from the Croatian Adriatic coast, in the vicinity of Rijeka, along the historical ‘Karolina’ road via Vrbovsko and Karlovac, all the way to Zagreb and onward via Krapina and Varaždin to the northernmost point of Croatia near Mursko Središće, with a natural continuation towards Budapest and Vienna. It was named the Zagorje route because it crosses the central part of the Hrvatsko Zagorje region in the section between Zagreb and Varaždin (direction south-north). The following description of the Zagorje route includes the section between Luka in the Zagreb County, where it intersects with the County route and extends further in the direction of Zagreb, and Bednja in the Varaždin County, where cyclists can make a turn for Varaždin and Trakošćan.
