TL;DR
  • Entry is by pre-booked time slot only
  • About 20 minutes from Keflavík airport, so ideal on arrival or departure day
  • Volcanic activity nearby can cause temporary closures, so check before you go
  • Condition your hair and keep it out of the water

The Blue Lagoon is a man-made geothermal spa in a lava field on the Reykjanes Peninsula, filled with warm, mineral-rich seawater from the nearby Svartsengi power plant. Silica gives the water its milky blue colour, and the bathing area stays at about 37-40°C all year, even when the air around it is well below freezing. It is one of the most visited attractions in Iceland.

What you'll see

The lagoon wraps around black lava rocks, with steam drifting across the surface. Inside the main lagoon you'll find:

  • A swim-up bar where your first drink is included in most packages.
  • The silica mask bar, where you can try the famous white mud on your face.
  • A sauna, steam room and in-water waterfall for a massage effect.

Premium packages add extra masks, a robe and a table booking at the Lava restaurant. For a quieter, pricier experience there is the Retreat Spa, and the nearby Retreat hotel.

Practical information

  • Tickets: entry is by pre-booked time slot only. The basic package costs from about £60-70 in 2026, varying with the time of day and season. Book on the official website and check current prices.
  • Getting there: about 20 minutes by car from Keflavík airport and 45-50 minutes from Reykjavík. Transfer buses run from both, and luggage storage is available on site.
  • Volcanic activity: since 2023 a series of eruptions near the town of Grindavík has led to occasional temporary closures. Check the Blue Lagoon's website and Icelandic Met Office updates on the day.
  • Best time to go: early morning or late evening for fewer people. In winter, an evening visit in the dark, possibly with the Northern Lights overhead, is magical.

The silica can leave hair stiff and tangled for days. Use the free conditioner provided, leave it in, and keep your head above the water.

Is it worth it?

The Blue Lagoon is expensive and busy, and locals tend to prefer smaller pools. But it is easy to fit in around a flight, and floating in steaming blue water surrounded by lava is genuinely memorable. If you're touring further, consider the Golden Circle with a stop at one of the region's natural hot springs too.

Frequently asked questions

Do I need to book the Blue Lagoon in advance?

Yes. Entry is only by pre-booked time slot, and popular times sell out, especially in summer and around Christmas.

How long can I stay?

There is no strict time limit once you're in. Most people spend two to three hours.

Do I need to shower before entering?

Yes. Like all Icelandic pools, you must shower without a swimsuit in the changing rooms before going in.
