Baredine Cave is a karst cave located near the town of Poreč in the Istria region of Croatia. Situated approximately 6 kilometers northeast of Poreč, the cave lies within the scenic Baredine Karst Field. It is a publicly accessible show cave managed as a natural monument and tourist attraction.
The cave extends to a depth of about 132 meters and features a network of chambers and passageways formed through the dissolution of limestone. It is known for its speleothems, including stalactites, stalagmites, and flowstone formations. The ambient temperature within the cave remains consistently around 14°C year-round.
Baredine Cave is home to the olm (Proteus anguinus), a rare and protected amphibian species adapted to subterranean aquatic environments. The presence of this endemic species contributes to the ecological significance of the site.
Visitors can explore a portion of the cave through guided tours that cover approximately 300 meters of the total system. The cave has been developed for tourism since the 1990s, with lighting and walkways installed to facilitate safe access while preserving the natural formations.
The site is part of the Geopark Istria, which emphasizes geological heritage and sustainable tourism in the region.
