Section length: 3 km
The section from the hydroelectric power station in Rutki to the hydroelectric power station in Żukowo is considered as moderately difficult. The riverbed is quite wide and deep, and the current is initially calm and then rapid. From now on, the Radunia River flows swiftly, with fallen trees and bushes quite frequent in its riverbed. Approaching Żukowo, the river meanders beautifully through picturesque meadows. This stretch is suitable for experienced kayakers. You arrive at the kayaking marina in Żukowo.
