Blue Lagoon is well-known for its vibrant blue water heated by the neighboring geothermal power plant, Svartsengi. Even though Reykjavík is the most populated city in Iceland, Blue Lagoon Hot Springs is actually closer to the Keflavík International Airport and is nearest to the small town of Grindavik. The water is blue in color because of the effect sunlight has on silica, which is acquired during the geothermal harnessing process.
