Námafjall
At the foothills of this spectacular volcanic mountain is an expanse of hot springs called Hverir that are known for their variety. You will also discover fumaroles, mud pools and mud pots that all seem to be boil with relentless energy. The pass Námaskarð is strategically located at a short distance from the Krafla volcano system as well as other interesting geological spots like Búrfellshraun lava field and the desert Mývatnsöræfi.
Námaskarð earns its notoriety chiefly because of its sulphurous mud springs called solfataras and steam springs called fumaroles. Though you will scarcely find any pure water spring in this wonderful geothermal site of Iceland, the beauty of the colourful minerals defies all comparison. The gigantic size of the mud craters is what makes you go 'wow' at the sight of them.
The other thing that is sure to strike you about Námaskarð is the sheer lack of vegetation. The constant emission of the fumes has made the ground utterly sterile and acidic, unfit to sustain any floras and faunas. You must bear in mind that the fumes can be harmful for humans as well.
