Hřebenec

Hřebenec is a small but geologically striking nature reserve in the Czech Republic, tucked about 8 kilometers southwest of Rožmitál pod Třemšínem. Protected as a natural monument since 1964, this rocky ridge sits at an elevation between 710 and 735 meters and forms one of the most distinctive features within the Třemšín Nature Park.

What defines the landscape of Hřebenec?

The heart of the reserve is a conglomerate rock ridge shaped into two clearly separated peaks. Along its upper section stretches a scree field roughly 600 meters long and 100 meters wide — an expanse of bare, weathered rock that gives the site an almost otherworldly, exposed character. Together with the surrounding slopes, this rocky terrain covers approximately 10 hectares, making Hřebenec compact yet remarkably concentrated in natural interest.

What kind of forest grows here?

Bordering the open scree is a relict pine forest, a woodland type that has survived here precisely because of the harsh, mineral-poor soil and challenging microclimate of the exposed ridge. Pines dominate the canopy, growing alongside birches, rowan trees, and spruces. This particular mix of species, uncommon elsewhere in this part of the Czech Republic, is a direct consequence of the thin, rocky substrate and the ridge's exposed position.

Why does Hřebenec matter to naturalists?

The reserve is best known for the rare invertebrates that inhabit its scree field. Hřebenec is home to the only confirmed population in the entire Czech Republic of the spider Comaroma simoni — making the site a singular refuge for this species nationwide. The scree also shelters Acantholycosa norvegica, a wolf spider classified as a glacial relict, a species that has persisted here since colder climatic periods and today remains characteristic of similar stony habitats across the region.

Where exactly is Hřebenec located?

The reserve lies within the municipality of Rožmitál pod Třemšínem, close to the villages of Roželov and Huť pod Třemšínem, as part of the wider Třemšín Nature Park. Its approximate coordinates are 49.5783°N, 13.7664°E. The surrounding area, known for its network of hiking trails through the forests and hills of the Brdy and Podbrdí regions, draws visitors looking for quiet countryside away from larger towns.

What should visitors know before going?

Because of its status as a natural monument, both the scree field and the relict pine forest are legally protected, so visitors are encouraged to stick to marked paths and avoid disturbing the fragile rocky habitat, which regenerates very slowly. Despite its modest size, Hřebenec is a vivid example of how specific geological conditions can give rise to a unique microecosystem found nowhere else in the country. For anyone interested in geology or rare invertebrate life, Hřebenec is a worthwhile stop near Rožmitál pod Třemšínem — a place where a bare rock ridge and a quiet pine forest come together to support species found nowhere else in the Czech Republic.
