Blue Lagoon in Iceland
It’s not hard to believe that this stunning turquoise pool has been considered a world wonder by National Geographic. Iceland’s Blue Lagoon is a man-made open air spa comprised of mineral-rich water and silica-rich geothermal mud. Located just 30 minutes from Reykjavik, it’s a great place to spend a few hours applying its white mud on your face, which is said to give you radiant skin.
