Habitats of Vjetrenica consist of cave channels, cracks, ground water and other living spaces in the underground. The temperature is constant, around 11 degrees Celsius, as well as humidity which is usually the maximum. Underground habitats are quite dark due to the lack of plants there is a constant relative scarcity of food. In Vjetrenica lives rich “cave” world, in which it is recorded almost 200 different animal species, of which 37 was first found and described at this place.

Vjetrenica is both the natural and archaeological site. Among the many archaeological finds there are also the remains of cave bears and leopards, cave drawings whose age is estimated at 10 000 years. The emergence of a strong “wind” at the entrance is a fascinating feature of Vjetrenica. In fact, it’s not the wind but the air flow, which equals a constant interior and variable outside air temperature. On the topographic surface above Vjetrenica there are deep cracks through which during summer enters the warm air, it cools and goes out through the main entrance of the cave. Wind speed in summer is up to 13 m/s. In winter, when the outside temperature significantly drops below the inside temperature, the wind reverses direction.
