Hi Matt, I haven't been there but I will be in Croatia with a car in March and April, so we're planning on checking out the area that the petzl roctrip went to in autumn. I think it's called Baille Herculane (the crag), and there is a multipitch area called the Turda Gorge nearby. I have to dash off now but if you know anything else, or would like to know about these two areas, ask me again in a couple of months!
