At the end of the Voje Valley, the Mostnica River spurts out of the rocks as a triple waterfall, known as the Mostnica Waterfall. On its lover limestone grounds, the river has cut out more than 2 km long channels that are the deepest at the Devil's Bridge (20 m) and quite narrow at some places (1m). What is especially worth mentioning is a rock that the water carved in the shape of an elephant.
