What is the name of Iceland’s famous geothermal spa near Grindavík?

The Blue Lagoon is Iceland’s famous geothermal spa near Grindavík.

The lagoon is a man-made bathing area supplied by mineral-rich geothermal seawater from the nearby Svartsengi power station. Its milky blue appearance comes from silica and other minerals suspended in the water, while the surrounding lava fields reflect Iceland’s volcanic landscape.

The first bathing facilities opened in 1987, and the site developed into an international spa and resort. The water is a by-product of geothermal power production rather than a naturally formed volcanic lake, an important distinction that is often overlooked.

The Blue Lagoon lies on the Reykjanes Peninsula, southwest of Reykjavík and close to Keflavík International Airport. Other Icelandic bathing sites, including Sky Lagoon and the Mývatn Nature Baths, are separate attractions.
