Blue Lagoon

Geothermal spa in a lava field near Keflavik airport, Iceland's best-known bathing destination.

The Blue Lagoon is Iceland's best-known geothermal spa, set in a black lava field on the Reykjanes peninsula. Its milky, mineral-rich water stays warm all year, and because the site sits between Keflavik Airport and Reykjavik it is a popular first or last stop on an Iceland trip.

Most visitors spend around two to three hours between the lagoon, the in-water features and the changing rooms.
What should I bring?
Bring a swimsuit and towel, both of which can also be rented on site, and shower before entering. Leave time to relax rather than rushing your booked slot.
