In terms of height this lovely falls is relatively small, with only a gradual 6m drop, but it stretches across the mighty Þjórsá river. It's the country's most voluminous waterfall at 360m³/s even though the water volume has been diminished by ≈ 50% because of the 5 hydroelectric dams built upstream.
