The Blue Lagoon is not a natural spring. It is the outflow of the Svartsengi geothermal plant: the water is pumped from two thousand metres, used to make electricity, then comes out at thirty-eight degrees, loaded with silica and algae. The silica is what makes it milky and stops it draining into the lava.
People started bathing in it in the 1980s, on their own initiative, before the site was developed. It is now the most visited paid attraction in Iceland, and it must be booked.
Getting there
Forty-five minutes from Reykjavik, fifteen from Keflavík airport. Many stop here on arrival or departure, leaving luggage in the lockers.
What the price covers
the Comfort package, first of three: entry, sauna and steam bath, silica mud mask, towel, private locker and one soft drink. Premium from 107 €, Signature from 132 €. The figure is a floor — it moves with the time slot — and pre-booking is compulsory.
What to bring
- Swimsuit
Rules on site
Entry is named, timed and booked weeks ahead: there are no tickets at the door. The silica wrecks hair — use the conditioner provided before going in, and tie it up.
