Iceland’s largest and most famous geothermal spa lies around an hour outside
Reykjavik, quite close to Keflavik Airport. With a dramatic setting amidst large black lava boulders, the steam-filled, creamy-blue pool area is a striking and surreal sight. The Blue Lagoon has been open since the 1980s and today draws some 700,000 visitors a year. The pools are actually created by heated seawater that flows from the adjacent geothermal power station. The waters allegedly cure all manner of skin-related ailments (eczema, psoriasis), but whether these claims are true or not, it’s certainly an atmospheric place to unwind, with very comfortable (99 degrees Fahrenheit) temperatures. The complex includes a small bar that dispenses healthy juices and beer, as well as a spa area for massages andbeauty treatments, and a very good restaurant; there’s also an upscale hotel if you wish to stay overnight.
