Biserujka Cave on the island of Krk is something worth visiting. Every weekend, when I drove towards Malinska, I kept noticing the sign for Biserujka Cave – the only karst cave on the island of Krk open to visitors. This warm Sunday was perfect for seeing it. Luck was on my side.
Biserujka Cave lies near the village of Rudine on the island of Krk. The route to it is signposted. Given that we are already in mid-November, I was convinced the cave would be closed. But I was wrong.
When I arrived at the entrance, they explained that the next descent into the cave would be in half an hour. Admission is €6, so I waited to see whether anyone else might turn up. Yesterday, after all, they had held the last tours of the cave for this year. In the end, a group of eight of us gathered and entered this interesting karst cave, 110 metres long, whose lowest point is 13 metres below the surface and which was discovered before 1850.
The temperature in the cave is between 13 and 15 degrees regardless of the outside temperature, and the relative humidity is 95 percent. For a long time, the cave was “open” to everyone, and it shows—people broke off stalactites and stalagmites—but since 1997, visits have only been possible with a guide and it is otherwise closed.
The cave is interesting, but once you have seen Postojna Cave, you see the whole thing in a completely different light. It is great that the guide explains it all quickly and entertainingly, especially when you realise that the oldest stalagmite is more than 500,000 years old. Two endemic species also live in the cave, although unfortunately I did not see them. The skeleton of a bear, from when they were still vegetarians, was also found in the cave itself.
I recommend a visit. Especially in summer, when it is hot outside, this must be a pleasant experience.
