Thanks for this. I have not climbed in Slovenia yet but hope to do so in the future. My friends say the Osp area is very good.
Glad you decided to post on UKC - we all benefit when info is shared across borders in this way. I notice that these new routes are not on the UKC database yet (click Logbooks at the top of the page and search for Crni Kal) It would be good if you had the time to add the details of these routes and any others you want to make more widely known to visiting climbers. That way there is a more long term record than just your current post.
