The "Krutynia Reserve" educational trail runs along the banks of the river to its confluence with Lake Krutyńskie. The route leads through a deciduous forest, which shows its advantages especially in spring, when the first spring flowers appear in the still dormant undergrowth. The narrow valley of the Krutynia River and the steep, high slopes of the ravine along the route show the effects of erosion processes caused by flowing water. Following the path, you can see the red thallus of the river hildenbrand on many of the stones. This species is under protection and its presence proves the purity of the river's waters. A watchful observer will notice colorful kingfishers flying over the water. On the river you can also see merganser, mallard ducks and mute swans. The path ends near the mouth of the river from Lake Krutyńskie. Nearby, there are the ruins of an old wooden bridge. In the past, the so-called rafting trips started here. up the river, which ended in the town of Krutyń.
