Blue Lagoon, Grindavík, Iceland

Let's be frank here, the origin of today's beautiful picture is a pool of wastewater from a nearby geothermal plant. While that may not sound enticing, Iceland's Blue Lagoon is one of the country's most visited attractions. The water here is clean, always hovers around 37° C and is enriched with tonnes of silica – which is what makes it blue – and sulfur thanks to the plant's processes. Those minerals, along with a little algae, are believed to combine into a highly beneficial tonic for skin and overall well-being.
