Bólugilfoss is a hidden waterfall in the Northwestern Region of Iceland. The waterfall sits in the Bólugil Canyon and is fed by the Bóluá river. We were unable to confirm the official name of Bólugifoss, but it is also known as Bólugil, Bólufoss, and Bólugilfossar. Google Maps shows the waterfall named simply as Bólugil Waterfall. It should be noted the National Icelandic Land Survey has an atlas that mentions the term “fossar.” Unfortunately, no definitive name was given there.
