The Namafjall geothermal field is located in Northeast Iceland, on the east side of Lake Myvatn.
At this area, also known as Hverir, you may see many solfataras and boiling mud pots, surrounded by sulfur crystals of many different colours. The area is quite smelly but something one gets used to after a while. The soil in the area has little growth and is sour due to erosion and the sulfur from the atmosphere. Indeed, the old rock-covered boreholes in the area give off a lot of hot steam.
Caution is advised.
