Iceland's world-famous geothermal spa, conveniently located near KEF Airport. Known for its milky-blue healing waters and luxury experience.
Story & Legend
Born accidentally from the runoff of the Svartsengi Geothermal Power Plant in 1976, this is now a National Geographic wonder. Locals noticed the warm, milky water cured psoriasis, and the silica mud is now patented for its healing properties. IMPORTANT: You must book your slot weeks in advance; walk-ins are almost never accepted.
Geology & Science
The water is a mix of 70% seawater and 30% freshwater, originating 2000 meters underground where it is heated to 240°C. It is rich in silica, algae, and minerals. The iconic blue color comes from the way silica reflects sunlight; on cloudy days, it looks greener.
Safety
Silica creates a barrier that makes hair stiff and unmanageable for days. Apply the provided conditioner GENEROUSLY and leave it in while bathing. Stay hydrated – the hot water makes you sweat even if you don't feel it.
Photo Tip
Use a waterproof case (GoPro or phone pouch). The steam provides a mystical atmosphere. For the most vibrant blue color, visit during the midday sun. For moodier shots, the twilight hour creates a contrast between the black lava and glowing blue water.
Insider Tip
Slather your hair in the provided conditioner BEFORE entering the water and don't rinse it out. The high silica content in the lagoon will turn unprotected hair into a stiff, unmanageable mess for days.
Best Time to Visit
Book the earliest possible slot (usually 8:00 AM). The water is cleanest, the changing rooms are quiet, and you get to watch the sunrise from the warm water.
What to Bring
Just your swimsuit and flip-flops. Towels are provided with all ticket tiers. Bring sunglasses; the glare off the milky blue water is incredibly intense on sunny days.
Frequently Asked Questions
Do I need to book the Blue Lagoon in advance?
Absolutely. Walk-ins are not accepted. You must book your timeslot online days or even weeks in advance, especially during the peak summer season.
Will the Blue Lagoon ruin my swimsuit?
No, the silica and minerals will not ruin your swimsuit, but you should rinse it thoroughly with fresh water and soap immediately after your visit to prevent stiffness and odor.
