There are many grottoes in Slovenia and some are very beautiful like the Zelske Grottoes. Through this interesting system of cavities you can reach one of the most romantic valleys, the valley of Rakov Skocijan. Old popular stories describe this strange place as the home of fairies, fiendish ghosts and witches. A group of speleologists go through this dark world,not to doanything exeptional or extreme, but merely to enjoy the romantic beauty of the place.
