Hólatungufoss is a waterfall in the south of Iceland. The waterfall is difficult to reach and is quit unknown. The waterfall is about 40-50 high and lies at the end of a glacier tongue of the Eyjafjöll.
From road 1, go to road 242 and turn of the road near the farm Rauðafell (jeep road) or walk to the canyon Kaldaklifsárgil in about 3 hours (ca 4 km). Hólatungufoss is further on near the glacier.
I can’t find the track on the map, but it should be there.
