Dynkur is a waterfall that it is about 38 m high in the Þjórsá River, southeast below the Kóngsá River in the Flóamanna district. The river flows over many ledges as small falls that together make one system of
waterfalls, but most important is the wondrous beauty and changeable rainbows that form so that it becomes an eruption of color over the falls when the sun shines. The people in the Holt area area call it Búðarháls Waterfall but those living in Gnúpver call it Dynkur (Thudding). It is best to view the falls from the east bank of the Þjórsár and then drive to Búðarháls from the bridge over the Tungnaá at Hald.
