The Biserujka Cave

It’s gotten a little chilly and we can only see the braver swimmers that don’t mind cold waters. Although the temperatures are not ideal for swimming, they are ideal for sightseeing and getting to know all the unexplored corners of the island of Krk. In this blog, we will be talking a little more about the Biserujka cave that is definitely worth a visit if you’re nearby.

The Biserujka cave is also known as the Vitezić or Slivanjska cave. It is situated in the north-eastern part of the island of Krk, above the Slivanjska cove, not far from the village of Rudine. The story says the cave got its name after the treasure found in it that belonged to the local pirates.

This cave is only several dozens of meters above sea level and very close to it. It is only 110 meters long and very rich in stalactites, stalagmites and columns. It is only 12 meters deep. The lowest part of the cave is 53 meters above sea level. Due to very thin “roof” (2-5 meters), on rainy days, the rainwater filtrates. The temperature inside fluctuates from 15°C in the summer to around 13°C in the winter.

The 16.000 year old remains of the cave bear were found in the cave, and it’s home to several endemic species of the Kvarner area. That is the reason it was listed in the National ecologic network that tends to preserve endemic sorts and habitat types – “karst caves and pits”. The cave is home to crabs, snails, centipedes and bats – so far, 28 species have been discovered in it.

The first time the cave was opened for visitors was in 1950. when its pit-like entrance was changed. But, even after that alteration, the cave was neglected until 1997. when the trails, fences and lighting were fixed, without which it would be impossible to see all its beauty. Since the last alteration and opening in 1997., the cave became one of the sights, cultural and natural values of the island of Krk. Besides the visitors from the island itself, it has many visitors from the Crikvenica Riviera too, coming by organized tourist transportation by sea. Thanks to it all, in the past 10 years, the Biserujka cave became one of the most visited caves in Croatia.
