The power of nature can be seen in all its glory at mighty Dettifoss, one of Iceland’s most impressive waterfalls.

Although Dettifoss is 'only' 45m high and 100m wide, a massive 400 cu metres of water thunders over its edge every second in summer, creating a plume of spray that can be seen 1km away. With the greatest volume of any waterfall in Europe, this truly is nature at its most spectacular. On sunny days, brilliant double rainbows form above the churning milky-grey glacial waters, and you’ll have to jostle with the other visitors for the best views.
