Engineers in Iceland have used the geothermal 36-40°C
hot water to create a 3.5
million litres
man-made lagoon.
There was only the very slightest trace of a sulphur smell.
The baths opened in 2004, but people had been taking baths and steam
baths in the area for centuries.
Another geothermal nature bath, The
Blue Lagoon, is one of
Iceland's biggest tourist attractions.
It is much closer to Reykjavik, but is not much visited by regular
Icelanders.
They find the Mývatn Nature Baths more intimate and
not as
touristic.
