The Blue Lagoon is without a doubt the most well-known geothermal spa in Iceland. The signature milky-blue water makes a stark contrast to the surrounding black lava fields and creeping grey moss. The spa is located in a lava field near Grindavík and is supplied by water used in the nearby Svartsengi geothermal power plant. The water temperature stays at 39°C year-round, snowfall or sunshine. Most visitors make the spa their first or last stop, since it's conveniently located only 15 minutes from the Keflavík International Airport (and around 30 minutes from the capital city). If you are buying a tour, it makes most sense to combine the spa visit with the Golden Circle day trip.
