Hydrological and hydrochemical research and monitoring

Monitoring of selected physical-chemical parameters of water by multifunctional probe Horiba; Oravecká Spring - Ponický karstWater is one of the most important components of cave geosystem. It is necessary for origin of caves spaces, formation of flowstone and ice fills and speleothems, existence of aquatic species of cave fauna. Water represents a transport media through the cave, which can be here accumulated during various time intervals. The karst waters are highly vulnerable. A problem of deterioration of their quality is many times connected with the reasons of gradual destruction of cave decorations and threatening the life of water animals.

Collection of seepage waters in the cave for determination of selected physical-chemical parameters in situ; Benikova CaveHydrological and hydrochemical research of cave systems resides mostly in monitoring of qualitative and quantitative character of attributes of karst waters and their potential changes in time and space, as well as in explanation of many time very complicated conditions of their underground circulation. The information on the character of these waters are substantial, since they can cause corrosion of carbonate cave fills. The knowledge of mutual relations and communication of surface and underground waters in the karst territory is important for interpretation of results. The outcomes of the hydrological and hydrochemical monitoring are used as entries in dealing with more complex tasks. The conclusions can be used as incentives for effective regulation of anthropogenic activities on the surface of karst landscape.

Monitoring of temperature and specific electric conductivity of occasional waters in the Suchá Passage of the Gombasecká Cave   The monitoring and research tasks are realized by the form of: (1) expedition measurements of several basic physical-chemical parameters of waters in cave environment, or waters directly related, (2) collection of samples with following interpretation of results, (3) continuous monitoring of regime changes of active and occasional water courses, levels of underground lakes and their selected qualitative attributes, (4) observation and mapping of karst hydrological phenomena (ponors, springs). Hydro-indicative tracing experiments are applied for reasons of finding out the underground circulation water ways, as a common method of karst hydrological research.

Hydrological and hydrochemical research of caves in Slovakia is provided mostly by the Slovak Caves Administration in Liptovský Mikuláš. Other vocational organizations participate on several research tasks. Within the problems of cross-border waters in the Slovak Karst we cooperate with the Aggtelek National Park administration in Hungary.


Demänovská jaskyňa slobody otvorená od 3.10.2023

Oznamujeme návštevníkom, že Demänovská jaskyňa slobody bude po rekonštrukcii elektroinštácie znovu otvorená od 3.10. 2023. Tešíme sa na Vašu návštevu.

Dear visitors, the Demänovská Cave of Liberty will be opened again from 3rd October 2023 after electric installation reconstruction. We are looking forward to your visit.


Dear visitors, our show caves are opened again from May 15, 2021 under the following restrictions: visitors must wear a face mask, disinfect hands and keep the required distance from each other. Details are stated in official country regulations and legislature. The number of visitors per admission is reduced. Thanks for understanding. We wish you a pleasant visit!

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.
