Travelers have been drawn to Iceland’s famous Blue Lagoon for decades, eager to take a dip in the steamy, mineral-rich water nestled in the heart of a lava field. Hundreds of thousands of visitors make the journey every year to experience the magical, intensely blue pools for themselves. Now, the spa is making plans to expand into a full-fledged resort with the 62-room Moss Hotel, a new Moss Restaurant, and a new spa called Lava Cove. The man-made lagoon is filled with the waste seawater released from a nearby geothermal power station.
