Dettifoss Waterfall Facts

Dettifoss has an average annual flow rate of 193m3/s, whilst at times it can reach an immense 500m3/s.

The flow of water from Dettifoss is so powerful that it makes the surrounding rocks vibrate.

Dettifoss is not the only beautiful waterfall located on the Jokulsa a Fjollum river; Selfoss is just upstream, whilst further downstream is Hafragilsfoss.

You may have seen Dettifoss before without even realising; it featured in the opening scenes of the sci-fi blockbuster Prometheus, which has led to some referring to it as the ‘Prometheus waterfall’.

The sheer power of the water flow creates a continuous water spray, leading to the manifestation of many rainbows, which only serve to amplify the splendour of the waterfall.

The water in the Jokulsa a Fjollum river is milky as a result of it being fed by the sediment rich meltwaters of the Vatnajökull glacier.

The Jokulsa a Fjollum is only the third largest river in Iceland by volume. However, the height and width of the Dettifoss waterfall have led to it being considered the most powerful waterfall in Europe.
