The Krąpiel river is a right tributary of Ina and on the section between Strachocin and Pęzino, is basically a winding and bending mountain stream. The river valley is deep, with steep, picturesque walls rising up to 30 m above the stream, and plenty of boulders and rocks on the bottom. The river is continuously fed by springs flowing from the lush valley slopes. The local flora is very rich and diverse, and the tree stand is predominantly deciduous. Efforts are being made to turn the valley into a nature reserve.
