The Romanian karst- Although the limestone rocks is spread over a relatively limited area (4500 km/~2800 miles) out of Romania’s overall surface (237500 km/~147575 miles), there are over 12000 caves and their variety and scenic passages are overwhelming.

History – although we find reference in the specialized literature dating from 1767, speleology truly blossomed since 1920, when the well-known Emil Racoviță established in Cluj the world’s first Institute of Speleology.

Soon after that, caving clubs were set up and this movement peaked in popularity in the 70s and 80s.

The setup of the Romanian speleologists

Romanian Speleology Federation has been established on the 28th of May 1994. There are 47 affiliated associations at the moment, in which Romanian speleologists take action.

There is a great diversity in Romania in terms of the community life, with plenty of events that take place throughout the year that allow you to interact with fellow speleologists.

The most important national events are: The National Congress of Speleology  and The National Contest of Artistic Speleology.

The schooling of these speleologists in terms of alpine technique, knowledge regarding the karst, cartography and biospeleology is done through The Romanian School of Speleology.

Banatului Mountains (Munții Banatului)

Reșița-Moldova Nouă area is Romania’s widest undivided surface abounding in karst. The myriad of caves and coves are medium and small-sized, without peculiarity.

The Comarnic Cave (Peștera Comarnic) is best known, spreading over 5.2 km/~3.2 miles and is in fact a hydrological perforation that can be wholly visited, entering through Ponicova Cave (Peștera Ponicova) and exiting through Comarnic Cave. The monumental chambers and the splendour of the stalactites & stalagmites are the cave’s main attractions.

Bihor-Vlădeasa Mountains (Munții Bihor-Vlădeasa)

Visiting procedures of caves in Romania

In Romania the caves are classified due to their speleological value estimated as following:

Class A – caves of utmost importance due to scientific interest or their peculiarity of resources and they count as national and international speleological patrimony.

Class B – caves of national importance that come to the front through their size, rarity or resources and touristic potential.

Class C – caves of local importance, protected for their geological, hydrological, historical significance or for their scenery and size.

Class D – caves that don’t meet the requirements to be included in A, B or C.

According to the legislation, all the caves need permit from the Committee of Speleological Patrimony, an organ empowered by the Romanian Government to write approval notices for tourists to visit the caves.
