Herzegovina is a rugged country in which limy layers originating in the Triassic, Jurassic, and Cretaceous ages extend for tens of metres. These layers spring up in spots, are sometimes crushed, or are in the form of large masses.
Water follows these rifts, disappears from the surface for a while, creates receptacles underground, or pours underground and crops up later on the surface as a whole river. From these sources the Herzegovinian Rivers - Buna, Tihaljina, Jasenica, Radobolja, Trebisnica, Vriostica, Bregava, Rama, Buka, Krupica etc. - well up. Some of these rivers, after a short flow on the surface, disappear again underground, and after a few kilometres, spring up on the surface again and receive another name.
The copious autumn rains, which fall in the area of Herzegovina, create streams. These make the rivers swell and flood, and the Karst expanses become lakes. The area of southern Herzegovina is more sparse regarding mountain springs. However, those water springs which it does possess present a real attraction, being more abundant than those of the mountains.
The waterways of Herzegovina are very attractive: Some, for the nature-lovers, some for the canoers, some for the fisherman, and others for those seeking a place to bathe, rest and refresh themselves.
