The winter landscape hits differently on Urridafoss. Usually flanked with lush greenery and wild flowers, Urriðafoss is a waterfall in the Þjórsá River. Þjórsá is Iceland's longest river, 230 km, and Urriðafoss is the most voluminous waterfall in the country. This mighty river drops down (360 m3/sec) by the edge of the Þjórsárhraun lava field in beautiful and serene surroundings. (Yes, all the "rock" you see is lava rock.) Þjórsárhraun lava field is the result of the greatest lava flow on earth since the Ice Age.
