Section length: 3 km (+1 km, Kaszuba, Zbrzyca)
The Młosina River is a left-bank tributary of the Zbrzyca River. It is best to start your trip in Leśno and finish in Kaszuba. The route is part of the Zbrzyca River kayaking trip. The Młosina is an easy and non-strenuous river. You set off from the village of Leśno, from the marina on Lake Leśno Dolne, and follow the shoreline and the historic shingle-roofed church with the tallest wooden bell tower in Poland (32 m) to the river outflow from the lake. You pass under a bridge, next to which is another marina (a good starting point). From the village, the route initially runs across meadows; further on, the river enters an area where you can see remains of a forest, destroyed as a result of the immense storm of 2017. You pass a wooden bridge and reach the mouth of the Młosina River at the Zbrzyca River. Then, the trip continues to the nearest marina in Kaszuba (1 km).
