The lagoon is an artificial construction; its bottom is covered by sand and gravel. The characteristics of the water are unique in many ways. It contains many minerals, is alkaline, and is well suited for bathing. Due to its chemical composition, undesired bacteria and vegetation do not thrive in the lagoon, making chloride or other disinfectants redundant.
Geothermal water in Iceland usually contains some sulfur. In this area, the strength of the chemical is more significant than others. Therefore it should be avoided to take jewelry from brass or silver into the water; they become black and can be damaged. Sulfur, however, is considered to have a positive effect on asthma and other respiratory diseases, and many of the trace elements in the water are believed to have a good impact on the development of skin problems.
The Steam Baths
The two steam baths are built straight on top of a geothermal area and the sulfur-free steam rises up through holes in the floor. Typically the temperature is around 50°C and the humidity is close to 100%. In spring 2019 they put windows in the steam baths so now everyone can enjoy the beautiful view.
Guests can take a few turns in the steam baths and cool down in the outdoor shower in between.
This is a perfect pit stop when you visit the so called Diamon Circle in the North. Soak in the Geothermal tubs at Myvatn Nature Baths. You can order drinks from the bar, making the experience extra cozy.
