Hunneberg has been a royal hunting ground since 1351, and the mountain has long been famous for its large elk population. The highest point of Hunneberg is at 155 metres above sea level. Hunneberg consists of sandstone, alum shale, and dolerite. The limestone and clay shale layers, usually found in the table mountains, are lacking here. But the dolerite layer is very thick, up to a maximum of 60 metres. The dolerite slopes give the mountain its characteristic appearance and favour a very special flora and fauna.
