Rječina River is about 19 km long. It springs from the cave at a height of 325 m above sea level, below the high cliff of Kičej hill (606 m above sea level). Until 1870 the river's spring was below the next hill, Podjavorje, but it collapsed in an earthquake near the village of Klana. In 1968 a dam was built to facilitate a hydroeletrical power plant creating lake Valići but destroying the village of the same name. Rječina flows through the canyon for almost half of her length.
To reach the source of Rječina River you can use a walking trail by river through the beutifull wood that takes you straight to the source.
It’s a great place if you want to escape from the city and the heat.
