Iceland is full of surreal sights and this photo from Svartsengi geothermal power station is a good example - it was discovered that the waste mineral-rich hot water from the plant was good for the skin so a spa called the "Blue Lagoon" is now located right next to the power station.
Apart from it's weird colour the water also has a high sulphur content which means the whole area smells strongly of rotten eggs.
