Dettifoss is the most powerful waterfall in Europe, with its massive 500 m³ of water thundering from the height of 44 m every single second down into a 100 m wide abyss. The spray of the water can be seen already several km away. The stark, rocky surrounding forms the perfect backdrop for such untethered natural power. About 1 km easy walking upstream is the humble and beautifully shaped Selfoss waterfall which stands in stark contrast to its thunderous companion. Hafragilsfoss is another amazing 27 m waterfall, located about 4 km downstream.
