Iceland's Blue Lagoon has been named by National Geographic magazine as one of the 'wonders of the world', reports Reykjavik.com.
A special edition of the magazine has included Iceland's stunning natural attraction in its list of the 25 most remarkable places around the globe for 2012.
Of the phenomenon, National Geographic wrote: "the steaming turquoise pools of Iceland's Blue Lagoon, trapped in volcanic rock represent an otherworldly vision" and that it is a "geothermal gift to nature", according to visitreykjavik.is.
The mineral-rich seawater, which originates 6,000 under the ground, contains 'unique active ingredients', silica and algae, all known for their skin-healing and health promoting effects, heybehappy.com writes.
A controlled flow means that the water is totally renewed within two days. Ever popular with visitors, a luxurious spa has been developed amongst the rugged landscape.
Also mentioned by National Geographic were the fjords of Norway, the Cave of Crystals in Mexico, Hawaii's volcanoes, the Sahara desert and the Northern Lights. Reykjavik is just 40 minutes away from the Blue Lagoon, offering visitors an unequalled holiday experience.
Boasting snow, beautiful scenery, a vibrant nightlife and the Aurora Borealis, it's not surprising that visitor numbers have increased year on year. 18 per cent more travellers came to Iceland in January, compared with the same month in 2011.
