Cave(rn) dive
Diving in cave(rn)s includes diving at depths and lengths of up to 40 m, but up to the point where divers can see.
The entrance should be clearly visible and accessible at all times.
Cavern diving is attractive in regions where there are small but interesting cave(rn)s that are not too deep or too demanding.
Such sites are a frequent phenomenon in the Croatian part of the Adriatic due to the karst relief and indented coastline and islands. Most of the well-known sites are found along the outer side of the islands
of the south Adriatic (Mljet, Vis, Lastovo, Korčula), as well as on the Islands of Dugi Otok, Cres and Krk. Smaller cave(rn)s are also found along the entire east coast of the Adriatic.
Apart from undersea cave(rn)s, there are numerous karst cave(rn)s in Croatia with springs. For diving in cave(rn)s, springs and at other speleological sites on land, a permit from the Ministry of Culture,
Department for Environmental Protection is supplied through one of the speleological organisations in Croatia.
