The waterfall Ófærufoss (the impassable waterfall) is one of the few interesting waterfalls in Iceland located in the Highland. It is a waterfall in the river Nyðri-Ófæra or “The impassable northern river”. Placed in the great fissure Eldgjá, or Canyon of Fire, a 40 km long eruptive fissure, is a geological phenomenon and one of the largest and longest fissures in Iceland formed in an eruption around the time of settlement in Iceland around the year 930. The part where we find Ófærufoss is the most beautiful part of the fissure, and also the most interesting as both the canyon and the waterfall are stunning. The canyon is around 600 meters wide and 200 meters height.
