The trail circles around the significant landscape of Kamačnik by Vrbovsko, through which flows the 3200-metre-long karst watercourse of the Kamačnik canyon. Starting from the Kamačnik restaurant, the trail follows an uphill route through lush vegetation above the canyon, then descends to the village of Senjsko on the Caroline road. After an around 1-kilometre ride on the main road, turn right toward the Dobra river valley.

The rest of the ride is along the route of the railway track and the Dobra river – an exceptionally beautiful and lovely watercourse with a diverse shore and river bed, as well as clear water.
