Hraunfossar Waterfall (Lava Falls) is a unique collection of countless rivulets cascading through a giant lava field (Hallmundarhraun) into the Hvita River over a distance of about 900 meters (2952 feet). This lava field flowed from the eruption of volcanoes beneath Langjokull Glacier.
Rather than a "traditional" waterfall, Barnafoss is actually a series of rapids on the Hvita River as it churns and twists through a narrow canyon (rocky basalt chute). September visits are enhanced by the autumn colors of the moss and foliage. Viewpoints along the shoreline provide stunning vistas and photo opportunities.
