Vysoký kámen u Smrčné

Vysoký kámen u Smrčné is a small nature reserve near the village of Smrčná, within the municipality of Vyskytná nad Jihlavou, in the Jihlava district of the Vysočina region. Despite its modest size, the site layers together three distinct stories — geological, ecological, and historical — within a single wooded hillside.

Location and elevation

The protected area sits at an elevation of roughly 630–650 metres above sea level, while the summit that gives the site its name, Vysoký kámen, rises to 660.7 metres. Geomorphologically the site belongs to the Křemešnická vrchovina (Křemešná Uplands), a range of low but rugged hills characteristic of this part of Vysočina, cut through by rocky ridges and stream valleys.

Rock formations shaped by frost, not water

Below the ridge that culminates at Vysoký kámen lie several rock formations that were not carved by flowing water or human hands, but produced by repeated freeze-thaw cycles over thousands of years during glacial periods. Water seeping into cracks froze and expanded, gradually splitting the bedrock into blocks and ledges. At the foot of these formations, accumulated debris has built up into extensive scree fields — loose stone slopes where the rock has settled but can still shift underfoot, so visitors are advised to tread carefully.

Why the forest is protected

The site holds dual protection status, functioning both as a natural monument and as part of the Natura 2000 network. It was designated to safeguard two forest habitats that rarely occur side by side: flower-rich beech forests of the Fagion association, growing on richer soils with a diverse understorey, and ravine/scree forests of the Tilio-Acerion association, which colonise the cooler, rockier slopes created by the frost-shattered debris. This second forest type favours lime and maple trees along with shade-loving plants adapted to unstable, stony ground. The coexistence of both habitats in such a compact area makes the reserve valuable for botanists and provides refuge for a number of rare plant and animal species.

Traces of medieval mining

Long before it became a protected nature site, the area around Smrčná was part of the Jihlava mining district, one of the more significant centres of silver and metal ore extraction in the medieval Czech lands. Mining activity here peaked in the thirteenth and fourteenth centuries. Remnants of old workings and spoil heaps are still visible in the terrain today, offering a tangible record of intensive extraction carried out more than 700 years ago — effectively an open-air trace of medieval industry hidden within the forest.

A lookout tower reduced to its foundations

A wooden lookout tower once stood on the rocky summit of Vysoký kámen. The structure itself has not survived, but the stone foundations on which it rested can still be found among the rocks at the top — the only remaining evidence of a time when this outcrop served as a vantage point over the surrounding forests and hills of the Vysočina uplands.

Frequently asked questions

How high is Vysoký kámen? The summit reaches 660.7 metres above sea level, with the wider protected area lying between roughly 630 and 650 metres.

What does the reserve protect? Flower-rich beech forests and scree/ravine forests growing on frost-shattered rock debris, home to rare plant and animal species.

Are there mining remains here? Yes — the area was part of the medieval Jihlava mining district, with the most intensive activity in the 13th and 14th centuries, and traces of old workings still visible.

Did the old lookout tower survive? Not fully — only the stone foundations remain on the summit rock, marking where the wooden tower once stood.
