Just before the Sázava River concludes its long journey and falls into the arms of its big sister, the Vltava River, it swoops around the Medník Hill. The hill is overgrown by beech and hornbeam-oak woods; however its greatest treasure is a tiny plant – the dog’s tooth violet. You can recognize this plant easily by its pink blossom with a yellow centre and unusually out-turned petals. The entire tiny plant usually boasts only two spotted leaves. Medník represents the only locality with the occurrence of the dog’s tooth violet in the Czech Republic and, at the same time, the most northern one in the whole of Europe. The plant normally bursts into blossom in March and April in the area called ‘V jámách’(‘In the Pits’). A number of other inhabitants live in the forests. The ring-snake may cross your path while searching for its most favourite pray – frogs and other amphibians near a small stream. However, the fire salamander has no reasons to be afraid, as its poisonous skin keeps it safe. A nature trail of an identical name passes through the Medník area. It will lead you to the foothills with an old gravel-sand terrace of the Sázava; the river flowed through this place millions of years ago.
