The reserve is located on the slopes of moraine hills, diversified by ravines, streams and springs. The Utrata stream flows through this area, which appears or disappears from the surface.
The aim of the protection is to preserve the Pomeranian beech forest in various typological varieties with rich associations of herbaceous plants in the ground cover. The beeches, over a hundred years old, reach a height of up to 40 m. Rare and endangered plants occur here, including forest fescue, empty corydalis, pearlwort, spearwort and common bedstraw. Among the protected plants, there are, for example, broadleaf helleborine, blue helleborine, guelder rose, common buckthorn and sweet woodruff. The bottom of the ravine is occupied by spring beech forest.
The reserve is named after Józef Lewandowski, an outstanding forester and pioneer in the development of the forests of Western Pomerania. The erratic boulder with a plaque commemorating this distinguished forest man is located in the southeastern part of the reserve, at the intersection of the roads from Szczecin-Śmierdnica and Kołów. For those who want to get to know the landscape of Kołowskie Parowy better, there are two hiking trails available. The Stanisław Pawelski Red Trail leads from Szczecin Kijewo to Glinna. The Stanisław Groński Blue Trail leads from Szczecin Zdroje to Zdunów.
