Speleotourism

In Armenia there are more than thousand caves, the length of a few meters to several kilometres. Of the natural caves, there are more karst caves, by their origin they are due to water, which washed away the soluble rock. Their main feature is the combination of wide halls with narrow passages. Another group of natural caves are volcanic or lava caves.
The caves were used by man since the epoch of the Lower-Middle Paleolithic, part of the caves were “landscaped” in the ancient and Middle Ages for the needs of pagan temples and monastic complexes.
The largest karst caves of the Republic of Armenia are found on the left bank of the Arpa River, such as Archeri, Magela, Mozrovi, Vaik and others. The part is located on steep and hard-to-reach slopes and one can reach them only on foot.
