Location: Reykjahlid and Myvatn lake area., .
Facilities: spa complex.
Description: Bathing lagoon: The water supplies for the lagoon run straight from the National Power Company´s bore hole in Bjarnarflag. The water has a temperature of about 130°C when it arrives to the huge basin beside the lagoon itself forming an impressive, man-made hot spring. Altogether, the lagoon and the basin contain around 3.5 million litres of water with 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 amount 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 redundant.
The two steam baths are built straight on top of a geothermal area and the sulphurfree steam rises up through holes in the floor. Typically the temperature is around 50°C and the humidity is close to 100%.
