The deepest cave in Croatia stretching over six storeys, of which the first 4 are open to the public. The length of the thus far discovered part of the cave is 1179 m, and the depth 275 m. The temperature inside the cave ranges from 6 to 8 degrees. Discovered 1911., Restored for tourism in 1912.

It was discovered by accident in the 1950s. It is estimated to be 3.5 – 4 million years old. Although measuring only 300 m in length, it is remarkably beautiful and rich in cave decorations. It is special for its water feature – a beautiful mountain spring, lake and ponor, which make it especially fascinating.

A small cave with a spacious 200 m long corridor leading deeper into the cave which ends in a small hall with a lake. The cave features some stalagmites and stalactites, and the water and air temperatures measure a steady 8 °C.

The history of this cave stretches far back into the past. The exploration of the cave uncovered a deer antler spike, as well as various remains of animals that used to roam this area, such as the cave bear and leopard. Traces of a hearth or a place used for lighting fire were also found, as well as burnt animal bones. All this suggests that the cave was frequented since as early as the later period of the Old Stone Age (Paleolithic).

Radiocarbon dating put the layers at 30 – 31 000 years before the present day, confirming human presence in these parts in early Upper Paleolithic.

The largest cave in Gorski Kotar, that is not easily accessible and therefore open only to speleologists. The spacious entrance to the cave is located opposite the Slovenian Kuželjska stena, in the steep cliffs of the peak of Belica. The entrance hall is 85 metres long, 27 metres wide and 16 metres tall and is one of the largest underground spaces discovered in our karst region. The network of channels and fissures, which have not yet been sufficiently researched, is about 900 metres long.

Kamačnik is a watercourse of incredible beauty, that has with time cut a canyon out of Jurassic limestone. It roars through the canyon over a series of small waterfalls and whirling potholes, especially when its waters rise after rainfall or melting snow. In the upper part of its valley, which it formed out of dolomite rock, the stream is somewhat calmer and receives a few smaller tributaries. The picturesque vauclusian karst spring is particularly valuable, as are the flora and fauna of its clean mountain waters. Visitors will enjoy the beautiful natural scenery – the rapids and small waterfalls, calm flow and clean waters, and the forests, flora and fauna.

Zeleni vir is a strong water spring at the bottom of a shallow and wide cave above the entrance of which rise 70 m tall vertical cliffs featuring a cascading picturesque waterfall.

Another attraction is the 800 m long canyon Vražji prolaz. Through this ravine gorge, two metres wide, a mountain stream flows among the rocks about a 100 m tall. The water has been flowing here for millennia, wearing away the rock’s surface and shaping this landscape that amazes every visitor with its raging waters and wild steep rocks.
