Dettifoss, Waterfall in Jökulsárgljúfur, Iceland
Dettifoss is a waterfall in the Jökulsárgljúfur canyon in northeastern Iceland that pours across roughly 100 meters of width as it falls into the black gorge. The water drops about 44 meters and creates constant mist that blankets the area in moisture from dawn through dusk.
The waterfall was carved by the Jökulsa River, which is fed by glaciers from Vatnajökull and has shaped this valley for thousands of years. The area was protected as part of Vatnajökull National Park in 2008 to preserve these natural landscapes.
The name Dettifoss means "falling water" in Icelandic and captures what visitors actually experience here: a powerful natural display thundering into the canyon. The black basalt walls surrounding the drop frame this dramatic landscape and make the place central to how Icelanders connect with their raw nature.
You can reach the waterfall from two sides: via the paved Route 862 from the west or the gravel Route 864 from the east, with the western path accessible year-round. The eastern route may become difficult in winter months, so check weather conditions ahead and wear sturdy shoes for the uneven ground.
On sunny days, water droplets create vivid rainbows arching across the black basalt, transforming the place into a spectacular display of color. This happens most often in the morning when sunlight hits the mist at just the right angle.
