It´s amazing how the flow of all that water can hypnotize you very easily sitiing there on the edge..WOW In my opinion the most magnificent waterfall in iceland.
The Dettifoss is a waterfall located in Jökulsárgljúfur National Park in North-Eastern Iceland. It is situated on the Jökulsá á Fjöllum river, which flows from glaciers. It is reputed to be the most powerful waterfall in Europe, having a flow variously estimated at between 200 and 500 cubic metres of water per second, depending on the season and the summer ice melt. The falls are 100 m wide and have a drop of 44 m.
