The colourful palette of the extensive Hornopožárské Lesy Forest attracts nature enthusiasts in the autumn period. An experienced eye can make out various types of forests – the oak, beech and fir woods. Foresters have been working in this area for a very long time; the trees of the forest were used as a source of wood for the nearby Jílovské gold bearing mines. A monument at the edge of the beech wood below the Panská Skála Rock commemorates the work of foresters. In this spot a forester called Dlabal met his tragic death at the hands of a poacher. Large granite boulders arrayed into bizarre shapes at the Gryble area will certainly not escape your attention. Round hollows can be found in many of them. These so-called ‘sacrificial bowls’ have inspired many varied legends. In the past their origin was attributed to the Celtic and even older settlements; however it is now known that they were created by the forces of water and frost. A valley with the mysterious name of Vlčí Rokle (Wolf’s Ravine) spreads out near the village of Kamenný Přívoz. Moss-covered granite boulders make up unusual groups and formations here, as if arranged by ancient giants. A path coils between the boulders where huge trunks of fallen beech trees obstruct the way. You can also find twisted and distorted European hornbeam and lime trees on the slopes of the valley. Only tough species of forest plants, such as the male fern, took root in the stony, shallow forest floor. Great spotted woodpeckers search for food in the tree trunks – looking for insect larvae. They also use their long scalpiform beaks for burrowing nests in suitable trees. Vlčí Ravine was established as a protected territory, and it is a nature sanctuary. Foresters maintain this area, carefully striving to preserve the original wild nature of this place.
