The current is quite calm, quickening only at times. Starting from Tłuczewo, the route changes. In entering a forest ravine, it speeds up giving rise to the most extreme section of the river. The steep slope, stony bed, and the numerous boulders create very strong and long rapids, and are a source of wonderful thrills – beware of the low water level, though, as it may pose a considerable problem. When the waters are high, experienced and assiduous canoeists will find this section a source of great joy and challenge. From Lębork, the river calms down again, becoming the perfect watercourse for one-day trips and for beginners. Family trips and water leisure is what this section is made for. The canoe route ends in Łeba, but the trip should conclude in Gać, as canoes are prohibited from entering Lake Łebsko. To cross the lake you need a special permit from the Director of the Slovincian National Park.
