The Cerovac Caves are located on the northeastern slopes of Crnopac, above the southern edge of Gračački polje
Upper Cerovac cave
The length of the explored channels is 4035 m, the total depth of the Upper Cerovac Cave is 192 m, and the total height difference is 202 m. The length of the tourist trail is 725 m. The entrance is spacious (10 x 6 m), located at an altitude of 671 m and oriented is towards the north. The entrance hall, about 30 meters long, stretches to the south. It follows the main channel, which then turns sharply to the west. There are several smaller and only two larger, secondary channels. At 237 m from the entrance, the 214 m long Medvjeđi rov separates from the main channel to the southeast, and after 400 m from the entrance, the Upper Hall separates from the main channel to the northeast, only about 80 m long, but over 15 m wide. In the Medvjeđi rov numerous cave bear bones (Ursus spelaeus) were found. The main channel continues to the west, and the last 200 m changes its direction to the northwest. At the 300th meter, the main channel expands into the Great Hall, and at the 400th meter, it expands into the Paleolithic Hunter's Hall. Cave bear bones were also discovered here, as well as very significant paleoanthropological and paleolithic finds (human bone, bone spikes).
In Medvjeđe rovo, about 60 m from the Main Canal, there is an entrance to a 100 m deep vertical. Narrowings and spacious, vertical channels alternate along the vertical. At the bottom of the vertical is the lower floor of the Upper Cerovac Cave. The length of the parts explored so far is more than 1500 m. It is a network of channels with a general north-south extension. The channels are rich in denudation (lat. denudare = bare; in geomorphology the collective name for all destructive morphological processes) (speleogenic) and accumulation (speleothem) forms. In part of these canals, there are also bone remains of animals, most likely a cave bear, but these findings have yet to be investigated. The southernmost parts of the lower floor are located very close to the surface, on the slope below the entrance to the Donja Cerovac Cave.
Lower Cerovac cave
The length of the currently known and topographically recorded channels in the Donja Cerovačka cave is 4058 m, the total depth of the cave is 68 m, and the total height difference is 97 m. The length of the tourist trail is 608 meters. The entrance to this cave is located at 624 m.a.s.l., it is smaller than the entrance to Gornja, and it is also oriented towards the north. From the entrance, the canal stretches to the southeast, and after 160 m it turns sharply to the west, and in the form of a spacious canal, it is about 750 m long. This channel is illuminated and arranged for tourists to visit up to about 600 m from the entrance, and it continues for another 50 m through a relatively narrower channel, which has been expanded in places by digging, at the end of which there is a vertical jump of 23 m. The morphology of the cave after this jump is significantly different : the cave here is formed into a network of canals and halls, and the main characteristic is the significantly larger dimensions of the space than in the tourist area. At about 850 m in length, the cave divides into two arms. One branch extends to the northwest, and in it is the main site of the remains of the cave bear, the Bear Hall and the large Mammoth Hall. The second branch extends to the southwest and represents the main channel of the cave, which consists of the Great Hall and the Cascade Channel, which ends in a narrow passage. Behind the passage is Pepeonik's channel, which stretches to the southeast, and towards the end of this channel, a narrow passage separates to the south, behind which are the newly discovered, southernmost parts of the cave. In the greater part of the cave, numerous vertical channels, the so-called chimneys (stumps), the tallest of which is 80 m high. The Donja Cerovačka cave is also filled with numerous scaly formations (speleothems) such as stalactites, stalagmites, columns, curtains, salves, cascades, pisolites (cave pearls), but also unusual and rare, eccentric
