Geoecological research and protection of caves

The caves represent specific natural geosystems with several special physiognomic features of geographical sphere components, spatial organization and natural processes. The caves are without pedogenetic processes and photosynthesis, and characteristical are special features of biocomponen­ts, speleoclimate, water as a part of hydrosphere and lithosphere with cave georelief in the zone of hypergenesis.

Demarcation of speleotopes, speleochores and sets of speleochoresCave geosystems are characteristic by spatial (vertical and horizontal) structure (speleotopes, speleochores, sets of speleochores) and time-spatial changes (seasonal regime, dynamics induced by the change of geoecological invariant, evolutional development in geological times). The knowledge on spatial structure and time-spatial changes of cave geosystems are important in dealing with various analytical and synthetical tasks, including environmental problems in karst landscape. The cave geosystems have strong relations with surface landscape systems. From the vertical point of view, it means mainly seepage of rainfall waters, from the horizontal one it means ponor autochthonous or allochthonous water courses.

Many anthropogenic activities influence natural processes, by which is the structure stability of cave geosystems disturbed. Among the most negative anthropogenic impacts belong: pollution of underground waters and damaging or even destroying of cave water fauna by sinking allochthonous water courses polluted by sewage from manure dumps and agrochemicals; seepage of atmospheric waters contaminated by agrochemicals or industrial imissions; disturbing of hydrological regime of seepage rainfall waters due to removing the vegetation cover, floating in soil sediments into cave spaces after deforestation or improper ploughing above the cave or within its catchment area, chemical destruction of dripstone fills by aggressive waters due to anthropogenic impacts, breaking off the flowstone fills, throwing waste into abysses, illegal collection of cave fauna, osteological and archaeological findings. Known are also cases of destroying caves by mining in quarries or at construction of roads. The regeneration capacity of karst landscape including caves is small, and in some cases impossible.

Speleomorphochores and a set of speleomorphochores in the Ochtinská Aragonite CaveSpeleomorphotopes in the Ochtinská Aragonite CaveThe self-regulation of cave geosystems and limit values of their resistance are important from the viewpoint of cave protection. On the basis of monitoring of these changes, the attendance of show caves is regulated and limited. Since the karst permeability in soluble rocks is connected with low filtration ability, the self-cleaning process of polluted underground waters is also low and in advanced stage of karstification is almost absent. The stability of speleotopes, speleochores and sets of speleochores is categorized on the basis of hydrological processes character, degree of karst permeability and character of further components of cave environment.


Card payment - recommendation

Dear visitors, we would like to inform you that due to the technical conditions of payment terminals, there may be situations when card payment will not be possible. For this reason, we recommend that you have an adequate amount of cash available if you want to be sure that you will be able to visit the cave. Thank you for understanding.

Demänovská jaskyňa slobody - long tour reopened from 1st July 2024

Dear visitors,

after a longer period we reopen the long tour in the Demänovska Cave of Liberty from the 1st of July 2024. The tour is open once a day at 13:15 from June to August (3 months) and at 13:00 during the rest of the opening days. Number of visitors is limited, the tour is demanding, with many steps and it takes more than one and a half hours. Cave temperature is around 7°C whole year round. We are looking forward to your visit. 

15. vedecká konferencia: "Výskum, využívanie a ochrana jaskýň" / 15th scientific conference "Research, utilization and protection of caves"

Konanie: 24.- 26. september 2024. Bližšie informácie o tomto podujatí nájdete na odkaze.

The conference will be held from September 24 to 26, 2024 in Liptovský Mikuláš. More on the link.

Cave visit with small children

Dear visitors, due to increased visitation of parents with very small children (circa up to 3 - 4 years of age), we would like to kindly ask you to have a rucksack baby carrier with you for visiting the more demanding caves in given time. This recommendation concerns all caves but the most concerned are the following ones: Demänovská Cave of Liberty, Belianska Cave, Dobšinská Ice Cave, Demänovská Ice Cave, Harmanecká Cave. We also ask you to consider visiting the cave with your crying child, which could disturb the other visitors. Thank you for understanding and we wish you a nice experience.
