A geothermal spa set in a black lava field on Iceland's Reykjanes Peninsula, its milky-blue water supplied by the nearby Svartsengi geothermal power station. One of the most visited attractions in the country, and a popular stop between Reykjavik and Keflavik Airport.
The lagoon's mineral-rich, silica-blue water sits at a warm bathing temperature year-round, whatever the weather above the surface.
The spa sits in a black lava field 5 km from the town of Grindavik, in front of Mount Thorbjorn on the Reykjanes Peninsula.
About 20 km from Keflavik International Airport, the lagoon is a popular first or last stop for travelers flying in or out of Iceland.
The Blue Lagoon requires advance timed-entry booking and regularly sells out, especially in peak season. Book directly through the official Blue Lagoon website.
The geothermal lagoon stays at a comfortable bathing temperature regardless of Iceland's often cold, windy conditions above the surface.
Its location between Reykjavik and Keflavik Airport makes it an easy add-on at the start or end of an Iceland trip.
The surrounding black lava field and steam rising off the milky-blue water make for a striking, unmistakably Icelandic setting.
Do you need to book the Blue Lagoon in advance?
Yes. Entry is by timed booking only and regularly sells out, especially in summer. Reserve directly on the official Blue Lagoon website.
How far is the Blue Lagoon from the airport?
About 20 km from Keflavik International Airport, making it a popular first or last stop on an Iceland trip.
Is the Blue Lagoon a natural lagoon?
It formed from water used at the adjacent Svartsengi geothermal power station, in a lava field on the Reykjanes Peninsula, rather than being a naturally occurring lagoon.
What's the water temperature like?
The lagoon stays at a warm, comfortable bathing temperature year-round, regardless of the air temperature outside.
The Blue Lagoon is a geothermal spa in southwestern Iceland, located in a lava field about 5 km from the fishing town of Grindavik and in front of Mount Thorbjorn on the Reykjanes Peninsula. Its distinctive milky-blue water is supplied by the nearby Svartsengi geothermal power station.
Around 20 km from Keflavik International Airport and roughly 45-50 minutes from Reykjavik by road, the lagoon has grown into one of Iceland's most visited tourist attractions, popular as a stop at either end of a trip through the country.
The Reykjanes Peninsula sits on Iceland's active volcanic system, and the region around the lagoon has seen periodic volcanic activity in recent years, so it's worth checking current conditions and any advisories before planning a visit.
