Nice hiking destination with great, near 360° views from the top. No technical difficulties, just sensible shoes and decent enough physical shape required.

The ruins of the old Baroque castle rise above the Unica River gorge in the southern part of the Planina Plain. The Hošperk Castle (Haasberg) was built by the Eggenberg princes at the beginning of the 17th century, at the foot of an old medieval castle that was destroyed by an earthquake. At that time, the castle was considered the most powerful Baroque castle in Slovenia. It was famous for its rich interior and beautiful park, which unfortunately is only partially preserved today. The last owner of the castle was the Windischgrätz family, who purchased it in 1846. During the Second World War, the nobles emigrated to Italy and the castle was occupied first by the Italian army, then by the German army, and in 1944 it was burned down. The valuable interior furnishings, the family archive and the family tomb of the last owners of the Windischgrätz Castle were completely destroyed.
