The Mystery of Biserujka Cave

Located near the village of Rudine, Biserujka Cave has been known for centuries. The first written record dates back to 1834, when it was mentioned in court documents as a hiding place for smugglers. According to legend, a hidden treasure lies within the cave, though it has never been found – hence the name Biserujka (biser = pearl).

Although relatively small (110 meters long and up to 15 meters deep), the cave boasts impressive natural decorations. Inside, you’ll marvel at the stunning calcite formations, columns, and stalactites, all illuminated to create an enchanting atmosphere.

A Unique Underground Ecosystem

Biserujka Cave is home to a rich variety of underground life, including six endemic species. Among them are:

Alpioniscus christiani – an underground crustacean,
Anophthalmus maderi maderi – an underground ground beetle,
Neobisium insulare – an underground pseudoscorpion.

In the cave’s lower channel, the remains of a prehistoric cave bear were discovered, offering a glimpse into the region’s ancient history.

A Cool Escape from the Summer Heat

Explore the Village of Rudine & the Stunning Slivanjska Cove
