10 Interesting Blue Lagoon Iceland Facts

By Aashima

The Blue Lagoon is the most popular tourist attraction in Iceland.

A must-visit for every traveler, the lagoon has many realities and facts that one might only know once they visit the site.

To help you avoid such mysteries and make your visit even more enjoyable, we have listed interesting facts about Blue Lagoon.

1. Blue Lagoon’s Origins

Not many know, but Blue Lagoon’s geothermal water originates from a volcano aquifer 2000 meters underground.

This is where the natural heating process begins: when freshwater and ocean water converge in a tectonic realm with extreme pressure.

The water consists of natural minerals like silica, algae, and sulfur that refresh, rejuvenate, and cleanse your mind and body.

Yes, you read it right! The lagoon is naturally equipped to cleanse itself.

The lagoon holds nine million liters of geothermal seawater, which is naturally cleansed every 40 hours.

A regular sampling of the lagoon’s minerals and resources explained how foreign bacteria cannot thrive in its water.

This is why this geothermal spa does not require chlorine for cleansing.

3. Blue Lagoon has Healing Properties

When Svartsengi opened the retaining pond as Blue Lagoon, no one imagined it would become a major tourist attraction.

One reason for its popularity was the rumor that it had medicinal properties for people suffering from skin diseases like psoriasis.

Since the water is rich in minerals like silica and sulfur, people believe the lagoon has skin-healing properties that benefit everyone.

But apart from the minerals, the lagoon today has many spa treatments that offer healing.

Many people come here to float away their mental stress and relax in the warm waters of Blue Lagoon.

Another significant fact about Blue Lagoon is that it is abundantly rich in minerals.

You can find high concentrations of silica and sulfur that give the water its milky blue color.

The mineral also has medicinal properties that can help people with skin diseases like psoriasis.

Other therapeutic benefits of Blue Lagoon are:

  • It reduces inflammation
  • Boosts your immune systems
  • Reduces stress and relaxes the muscles
  • Soothes your skin 
  • Improves blood circulation

4. It is a Man-made Phenomenon

Given its healing properties, it is surprising that Blue Lagoon is not a natural hot spring.

Although the land and lava are instrumental in making the lagoon natural, the water is not.

Blue Lagoon’s water is the result of volcanic formation and geothermal plants.

To explain in simpler terms, a geothermal plant uses a volcanic landscape to generate heat and power.

Once the water goes through the turbines, it cannot be reused again for energy production.

The heated water is due to the plant’s runoff filtered directly into Blue Lagoon.

But worry not, as this runoff contains no dangerous or toxic pollutants.

5. Blue Lagoon is in Keflavik and not Reykjavík

Another interesting fact about Blue Lagoon is that it is in Keflavik, not Reykjavik.

Various buses from the Keflavik airline terminal will take you to the lagoon before heading to the central city or returning to the airport.

On the other hand, if you plan on traveling from Reykjavik, you will have to drive for 45 minutes to the lagoon.

Most public transportation from Reykjavik does not have access to the Blue Lagoon.

This is why we recommend you book a ticket with airport transfers to avoid the hassles of arranging vehicles.

6. Its Warm Temperature

The Blue Lagoon’s temperature usually ranges from  37°C to 40°C (98-104°F).

This tends to change depending on the weather or season. The temperature can fluctuate beyond its usual heat.

Nonetheless, the lagoon will remain calm, warm, and relaxing throughout the year.

7. A Must-Nude Shower Ritual

Yes, you read it right. Every visitor must follow this rule.

As one of the most visited lagoons in Iceland, the shower stalls have locks that give you all the privacy you need.

Once you shower, you can wear your bathing suit and enter the lagoon without hesitation.

Moreover, Blue Lagoon staff members are placed around the shower stalls to ensure security.

Tip: If you have an issue showering in cubicles, buy the Retreat Spa ticket to get private changing rooms.

8. It is not Ordinarily Famous, but Movie Famous

One interesting fact about Blue Lagoon Iceland is that it is a big movie star.

It is not only a thermal spa but also a gorgeous location that manages to attract several filmmakers.

You may have spotted this luxurious lagoon on the TV reality series Amazing Race and Britain’s Next Top Model, as well as in movies like Hostel – Part III and the documentary Look Alive.

This way, they can monitor how it environmentally impacts the geothermal production in Iceland.
