Hengifoss is a waterfall in the East of Iceland near Neskaupstaður. The river Hengifossá in Norðfjörður falls down over 30 meters in a very beautiful and luxuriant ravine. I think this is upstream from Hengifoss. Hengifoss i Norðfjörður is an official named waterfall.
When coming over Oddskarð (road 92)and driving down to Neskaupstaður (from the south to the north), Hengifoss is on the left 5 km down hill from the top.
