Dettifoss is a waterfall situated in Jökulsárgljúfur National Park, in the Mývatn area of north-east Iceland. It is located on the river Jökulsá to Fjöllum. It wasn't easy to get there because I looked for the river side with the worst access. A horrible road that is sometimes even closed. But this is without a doubt the best view for this fantastic and dangerous cascade.
