Speleological tourism is a specific type of tourism. This type of tourism, as a segment of the tourist offer, contains unique and unique motives, which are mostly available to a small number of people. Starting from the goal and the number of visitors, we can single out different subtypes of speleotourisms, such as esthetic, sports, educational and...

Speleological objects, in the narrower sense, are considered to be caves and pits as underground forms of relief created by the karst process. Horizontal and subhorizontal underground channels are called caves. Pits are called vertical and subvertical channels. In the world (English-speaking world), the single term “caves” has long been accepted fo...
