The famous Blue Lagoon geothermal spa is just 20 km from the airport, making it perfect for a layover visit.

About Blue Lagoon

The Blue Lagoon (Bláa Lónið) is Iceland's most visited attraction, a geothermal spa where visitors bathe in milky, mineral-rich water (averaging 37-39°C/98-102°F) surrounded by a stark black lava landscape. The distinctive blue color comes from silica, algae, and minerals in the geothermally heated seawater. The silica mud masks, swim-up bar, and steam caves add to the otherworldly experience.

Located on the Reykjanes Peninsula, the Blue Lagoon sits almost exactly between Keflavik Airport (20 km) and Reykjavik (30 km), making it a perfect first or last stop on any Iceland trip. The facility includes the Retreat Hotel (a luxury hotel built into the lava), the Lava Restaurant, and a spa shop selling the Blue Lagoon's skincare line.

Advance booking is mandatory—the Blue Lagoon operates on timed entry tickets and frequently sells out weeks ahead during peak season (June-August). Three ticket tiers (Comfort, Premium, Retreat) offer progressively more amenities. The spa is open year-round, and winter visits with snow on the lava and potential Northern Lights overhead are especially atmospheric.
