Yes! Pre-booking is mandatory. The Blue Lagoon often sells out days or weeks in advance, especially in summer. Book online as early as possible to secure your preferred time slot.
The Blue Lagoon is man-made, formed from the silica-rich wastewater of the nearby Svartsengi geothermal power plant. However, the geothermal water and minerals are completely natural, and the unique healing properties were discovered by accident.
