Losky

Losky is a small geological natural monument located along the road connecting Ježov and Osvětimany in the Hodonín District of South Moravia, Czech Republic. Despite covering just 0.07 hectares, this tiny protected site preserves a scientifically valuable exposure of Quaternary loess deposits.

What exactly is Losky?

The site is the abandoned eastern section of a former clay pit, once worked for loess used in construction. Excavation left behind a steep wall roughly 23 metres high, revealing several sedimentary layers, including horizons of fossil soils and their derivatives. This layered profile lets researchers trace climatic and environmental shifts that occurred in the region thousands of years ago, which is why the site holds particular value for geologists and paleoclimatologists rather than for casual sightseers.

Why are there caves in the wall?

Two small, artificially dug openings appear in the middle section of the exposed wall, resembling miniature caves. The larger of the two is accessible via a steep wooden staircase fitted with a handrail, allowing visitors to approach the opening safely without disturbing the surrounding loess formation.

Where is Losky located?

The monument sits about 200 metres southwest of the Horní Ježov water reservoir and roughly 1,200 metres southeast of the centre of Ježov village. Its position along the road toward Osvětimany makes it easy to combine a visit here with a walk around the reservoir or the surrounding countryside.

When and why was it protected?

Losky was officially declared a natural monument on 12 September 2002. It falls under the administration of the Regional Authority of the South Moravian Region. Its small size and designation as a "natural monument" rather than a larger reserve reflect the nature of the site: not an extensive ecosystem, but a compact, geologically unique exposure worth preserving in place.

What should visitors know before going?

Losky appeals mainly to those interested in geology and landscape history rather than being a typical scenic destination. Visitors should take care on the steep staircase leading to the cave opening and avoid touching or disturbing the loess wall, since the exposed sediment layers are fragile. Given its small footprint, a visit typically takes only a few minutes, making it a natural addition to a longer route through the Ježov area.

Frequently asked questions

How is Losky different from the nearby quarry in Ježov? Losky is a former clay pit exposing loess sediments, while the Ježov area also contains other, separate geological sites nearby — they should not be confused despite their proximity.

Can you enter the caves at Losky? The larger of the two openings is reached by a wooden staircase with a handrail, which allows safe access to the entrance.

How do you get to Losky? The site lies along the road from Ježov to Osvětimany, near the Horní Ježov water reservoir, so it is easiest to reach on foot or by bike from the village centre.

Is there any tourist infrastructure on site? Due to its small size and its status as a natural monument, the site has minimal infrastructure — the wooden staircase to the cave opening is the main visitor aid.
