Mramornica cave is one of the largest caves in Istria and was already mentioned as early as 1770 by the famous travel writer Alberto Fortis when he visited and described this cave. Close to Brtonigla, after the nearly vertical steps, stands the entrance to one of the largest underground halls in Istria. The cave is rich in different coloured drip-stones, stalagmites that are as much as 13 meters tall making Mramornica particularly fascinating and attractive. From the well-kept paths, with safety railings, of the cave there is a view of the inaccessible parts, which because of this secretiveness are even more alluring. A great place to visit for everyone loving the mysterious wonders of nature!

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. Take a warm vest or jacket in summer months as the temperature in the cave is at a constant 13-15 C.
