My favorite place to visit after a good day exploring around Mývatn.
The water supplies for the lagoon run straight from the National Power Company´s borehole in Bjarnarflag. The water has a temperature of about 130°C when it arrives in the huge basin beside the lagoon itself forming an impressive, man-made hot spring. The lagoon’s water has a temperature of 36 – 40°C.
The lagoon itself is a man-made construction, its bottom is covered by sand and gravel. The characteristics of the water are unique in many ways. It contains a large number of minerals, is alkaline and well suited for bathing. Due to its chemical composition, undesired bacteria and vegetation do not thrive in the lagoon making chloride or any other disinfectant not needed.
