Mramornica Cave in Istria

Mramornica Cave - a karst beauty

When passing through Brtonigla don't miss the opportunity to visit Mramornica cave, considered by many speleologists to be one of Istria's largest and loveliest subterranean structures.

Mramornica - one of the largest caves in Istria

Mramornica Cave was first mentioned in the writings of travel writer Albert Fortis in 1770. Today, it is open to both the young and the old seeking for adventure. From the very entrance of the cave, a steep stairway leads down to a large chamber filled with dripstone formations of different colours and huge stalagmites some 13 metres tall and up to 10 metres wide.

The trails leading through the cave are well-maintained and equipped with safety railings from which you can peer into the cave’s mysterious but inaccessible parts that reach down to inconceivable depths.

To find your way to Mramornica Cave, just follow the signs leading to the Sterle agritourism farm where the cave is located. Nature lovers will enjoy the refreshing chill of the cave’s underground chambers, and the whole family can take pleasure in the various activities offered at the Sterle farm.
