The Blue Lagoon

The Blue Lagoon is a geothermal spa fed by seawater from the nearby Svartsengi power plant, rich in silica and algae that give it the famous milky-blue colour. Entry is by pre-booked time slot and packages include a silica mud mask, a towel and a drink; more expensive options add a robe and lounge access. Because it lies between the airport and Reykjavík, it is easy to visit on your arrival or departure day, with luggage storage at the car park.

Volcanic activity: the Blue Lagoon has closed temporarily several times since 2023 because of eruptions on the nearby Sundhnúkur crater row. Check the Blue Lagoon website and safetravel.is shortly before your visit.

Combine the Blue Lagoon with your airport transfer: buses drop you at the lagoon and take you on to Reykjavík or the airport.

Blue Lagoon alternatives

Sky Lagoon in Kópavogur, near central Reykjavík, has an infinity edge over the ocean and a seven-step sauna ritual. Further afield are the Secret Lagoon on the Golden Circle and the Mývatn Nature Baths in the north. See our hot springs map.

Volcanoes on Reykjanes

After 800 years of quiet, the Reykjanes Peninsula woke up in 2021 with eruptions at Fagradalsfjall, followed by repeated fissure eruptions along the Sundhnúkur crater row north of Grindavík from December 2023. Lava has cut roads and reached the edge of Grindavík. When an eruption is under way, authorities decide whether viewing areas are open; never walk on new lava, which stays hot for months, and beware of toxic gas. See our volcanoes map.

Guided tours of the peninsula visit the lava fields, geothermal areas and lighthouses, and adapt to current volcanic activity.
