The Myvatn basin sits squarely on the Mid-Atlantic Ridge. Although most of the interesting sights are volcanic or geothermal features, the centrepiece is the 37 sq km lake Myvatn itself, which averages a depth of only 2.5m. The lake contains over 50 islands and islets, mostly pseudocraters formed when molten lava flowed into the lake. Places of interest include the pseudocraters at Skutustadir,Hofdi peninsula, Dimmuborgir lava formations, Hverfell Crater, Hverir hotspring area, Krafla volcanic area and Myvatn Nature Bath.
Myvatn is considered one of the best birdwatching place in Iceland.
