Biserujka Cave is located on the island of Krk 300 meters north-west of the Rudine village. The cave is adjusted to tourists and offers a wealth of cave decorations - calcareous sinters, stalagmites, and stalactites. According to a speleological classification, it represents a simple cave with mouth that lead into a gently sloping cave channel. Its underground areas include: Mouth, Balcony, Shaft, Great Hall, Northern Channel, Arched Hall and Cypress Hall.

Biserujka Cave is also known as Vitezićeva Cave. The lowest point of the cave was measured at -13 meters, and the bottom of the cave is only 30 meters above the sea level. The cave extends relatively shallow beneath the surface and its overlay never exceeds 6 to 8 meters. Bone fragments of a cave bear (Ursus spelaeus) were found in the cave.

In the deeper part of the cave variations of microclimatic parameters are minor; soil and air temperature is about 15.0° C with relative humidity of about 95%, which makes the cave environment quite enjoyable. Endemic wildlife of the cave is very diverse. Six stenoendemic species live in the cave (endemics of a very narrow range endemic to the Kvarner area). Three species of invertebrates from Biserujka Cave are described, thus making this cave a type site (“locus typicus”). In 2009 an unknown species of pseudoscorpion belonging to the Roncus genus was discovered in Biserujka. Because of it the cave was listed in the National Ecological Network aiming to preserve endemic species and habitats - karst caves and pits.
