This trip circles the conservation area called „Fjallabak“ or „Behind the Mountains“ in the central highlands of south Iceland. The area is one of the largest geothermal areas in the world, framed in by large glaciers, hence a place of great contrasts. During the trip we pass some of the very well known attractions of Iceland like one of our most active volcano mt. Hekla, Landmannalaugar with it‘s natural geothermal pool, Eldgjá, Þórsmörk and Skógarfoss. During the drive out we visit the great Gullfoss waterfall and the Geysir area with spouting geysers and boiling hot springs. The biking is mostly on dirt and gravel roads, with many unbridged rivers and the last two days involving considerable single-track sections. This is a demanding mountain biking trip that requires fitness and at least some mountain-biking experience.
