The Castle to Castle Route was formed in 2014 and stretches in a circle from Varaždin and then onto Lepoglava, Trakošćan and Cvetlin before returning to Varaždin. Cycling signposts have been placed along the entire track, and the route has also been mapped onto an on-line cartographic system in GPX files which can be downloaded onto navigational devices and shows all relevant route data, such as special points of interest, route length and elevation, the type of substrate and the like. On this Route there are two self-service stations – Varaždin and next to Hotel Trakošćan. The aim of this Route is to connect recreation with the cultural-historical, natural and geomorphological sights of Varaždin County.

The Cycling Route from Castle to Castle is 85.6 km long. The entire road section for this Route is suitable for cyclotourism activities in both directions.
