Slovenia

In Slovenian Istria exist four official climbing locations: the granddaddy of Slovenian climbing – Črni kal, popular Osp, the queen of Slovenian hardest testpieces – Mišja peč and infamous sinkhole Risnik.

Besides that you can always try to search for information between local climbers about secret cave Skedenj near Sežana which is perfect summer destination for hard-core climbers.
