Contrary to popular beliefs, The Blue Lagoon is not one of Iceland's abundant natural springs, even though the land and lava played a major role in its formation. In fact, it was man-made in 1974 as a drainage site for a nearby geothermal power-plant. Located 45 minutes outside Reykjavik, the Lagoon’s volcanic surroundings richly provides its waters with minerals. Indeed one of the causes of its popularity thanks to their healing virtues, the Blue Lagoon and its milky waters are still one of Iceland's most visited touristic sites.
