Among the cycling routes of county significance the most important place holds the Circular county route that connects all four routes of the state significance and both cross-border routes, and with its 163 kilometres it is the longest route in the Krapina-Zagorje County. Its most attractive sections are on asphalt roads with little traffic. Since many parts of this route lead over the ridges of Zagorje hills with nice views, there are many ascents and descents on it, so it is not recommended for bikers out of shape and it is recommended to divide it into several days.
