Hike around craters and cooling lava at Iceland's Fimmvorouhals Volcano in Thorsmork Valley! The exciting day trip includes round-trip transport by 4x4 jeep from Reykjavik as well as a stop at Seljalandsfoss Waterfall near Eyjafjallajokull Glacier. After arriving at Basar in Thorsmork Valley, set off on a 12-mile (20-km) hike, taking in spectacular volcanic scenery. The paths are relatively easy and not too steep, but good general fitness is required.
