Sini Vir is about an hour away walking distance west of the Medven village in the valley of the Kanina river (also called Karvava reka, meaning bloody river). The falling water has formed blue-green colored coves. This waterfall is more of a cascade along the river which in this area has created a small and charming gorge. For 3 kilometers the river makes its way among unreachable vertical rocks hanging over it. There are a few caves around, and several pines have found a way to survive here on the rocks.
