The Lake Mývatn area is widely known for its natural beauty. In this bus tour that starts in the port of Akureyri we provide the chance to explore the highlights of the area with an experienced, local tour guide. The first stop is at Goðafoss waterfall, not only famous for its breathtaking beauty but also for its significant historic value related to the Christianisation of Iceland. From Goðafoss the tour continues through the valley of Reykjadalur to Skútustaðir in the Lake Mývatn district. There we explore the regular shaped pseudo craters formed in a volcanic eruption approximately 2300 years ago. Next the tour continues to Dimmuborgir (The Black Castles), a lava labyrinth formed around 2300 years ago when a partly cooled lava lake drained out and left magnificent basaltic pillars and sculptures. Next we explore the fumarole fields of Hverarönd (Námaskarð) where ground water is heated  by an underground magma intrusion. Sulphur deposits are brought to the surface and the area is characterized by a strong smell of sulphur.
