Dettifoss is the most powerful waterfall in Iceland and is very impressive to see with a width of 100 m a height of 44 m high. There are different viewpoints, but the best view points are on the east side of the river.

Dettifoss is located in Iceland’s second largest river Jökulsá Fjollum (206 kilometers) fed by the glacier Vatnajökull. The muddy water squeezes itself through a narrow canyon with an average volume of 193 m3 per second and ends in the Arctic Ocean. The area is part of the Jökulsárgljúfur (glacier river gorge), since 1945 and one of the four National Parks of Iceland.

It is said that Dettifoss is the most powerful waterfall in Europe with possible volumes up to 500 m3 per second.

Dettifoss is located on the Diamond Circle, a popular tourist route around Húsavík and Lake Mývatn in North Iceland. From the ring road, take the 864, a dirt road, for 27 kilometers. Very dusty, but really cool to drive. You can’t miss the exit for Dettifoss and is well marked. Do not forget to check the  Hafragilsfoss, a little bit further to the north. Not as powerful, but still very beautiful.

Dettifoss is not the only waterfall in the river Jökulsá Fjollum. Upstream (1 kilometer/20 minute walk) you will find the Selfoss. Downstream there is another impressive waterfall Hafragilsfoss. A little bit further downstream you will also find Réttarfoss, even so impressive as the other falls (but Dettifoss is of the outer category)
