Velebit caves
The "Lukina jama" cave is 1431 m deep (2013), the deepest cave in Croatia, 14th deepest cave in the world and the deepest cave in southeast Europe. At its foot, there are ponds and streams including one of the largest known colonies of subterranean leeches ("Erpobdella mestrovi"), which has been ascertained to represent a new species, genus and also family. Other species discovered in the system, include the air-breathing land snails "Zospeum tholussum". Like Lukina jama, Slovacka jama, Velebita and Meduza are also located at the "Hajdučki i Rožanski kukovi" special reserve, a dedicated part of the Sjeverni Velebit national park.
Baredine Cave
The sightseeing lasts 40 minutes, visitors descend along a 300m long pathway up to 60m below the ground and an underground lake and visit 5 beautifully decorated chambers.
An interesting detail of this adventurous trip is also the encounter with the underground world of animals: visitors will see the cave olm (Proteus anguinus Laurenti), endemic in this dinaric karst region- an animal that can be found only in this karst area.
In one of the chambers you will pass along a 4m wide passage that leads 66m vertically down reaching the deepest point of the cave at 132m.
