Kolufossar is less well-known, but definitely worth a visit. Kolufossar is an 8-meter-high waterfall in the Víðiðalsá/Vididalsá River. The gorge is about 1 km long and 40–50 meters deep. According to legend, the gorge was created by the troll woman Kola. The legend further states that the troll Kolugil and his treasures are buried there, and that the hill is protected by a spell cast by the troll.
