In the valley of the river Radika, in the Reka region, at the foot of the Deshat Mountain, in the national park Mavrovo is located the mountain village Rostushe, in the immediate vicinity of which is the natural rarity and beauty - Duf waterfall. What makes this waterfall special and separates it from other waterfalls is the height of the rock from which the water falls. As it falls the water from that height creates an incredible sound and view, which reminds us of something very powerful and grandiose. Nature creates wonders, and so this Duf waterfall was created. In the spring, the image of the waterfall and the feelings that it brings to the visitors are much bigger and real. This phenomenon occurs with the melting of the snow, the water rises and it is almost twice increased compared to the usual level, so it gives a much more impressive feeling.
It is an erosive waterfall, created as a consequence of the regressive retention of the river bed of Rostushka River. According to the geological structure, the most common are carbonate rocks. The total vertical section of the Duf Waterfall is 23.5 m, and the foot part contains a giant pot. The Duf Waterfall is full of water during the whole year, whereby the flow is twice as high in winter, and on average it is around 90 l/s.
