DETTIFOSS is my favourite waterfall. It is located in northeast Iceland to the east of Lake Myvatn, about one hour off the ‘Ring Road’ and is consifdered to be the most powerful waterfall in Europe with a flow of 193 cubic metres per second going over the 100m wide falls, dropping 43m into the gorge of the Jökulsa á Fjöllum River (Sarp Falls in Norway has a bigger flow but only stands about half the height of Dettifoss). The Jökulsa á Fjöllum is a glacial meltwater river emanating from the Vatnajökul Glacier and its water is consequently grey-white with sediment. Standing next to the thundering giant Dettifoss is a terrific experience, especially on the quiet eastern side of the falls. The western side is nearer to Lake Myvatn for the day-tripping bucket listers from the Husavík cruise ships and is best avoided at peak times. The view is better by far from the eastern side in my opinion as well.
