Why is the Blue Lagoon Blue

he Blue Lagoon's distinctive blue color is due to the unique composition of its geothermal waters, which are rich in silica and other minerals.


Here's a breakdown of the factors contributing to its blue hue:

  1. Silica: The primary cause of the blue color is the high concentration of silica particles in the water. Silica reflects visible light, giving the water its milky blue appearance. The fine particles of silica also scatter sunlight, enhancing the blue effect.
  1. Algae and Minerals: In addition to silica, the lagoon contains minerals and algae that can influence the color. While the algae can sometimes give the water a greenish tint, the overall effect of the minerals and silica predominates, resulting in the characteristic blue color.
  1. Geothermal Activity: The water in the Blue Lagoon comes from a nearby geothermal power plant, which draws from underground reservoirs. The combination of seawater and freshwater is heated by volcanic activity, enriching it with minerals that contribute to the lagoon's unique properties, including its color.

The interplay of these elements creates the striking and memorable blue color that the Blue Lagoon is known for.

Is the water warm?

Yes, the water in the Blue Lagoon is warm. It typically ranges from 37 to 40°C (98 to 104°F), which is comfortably hot for soaking and relaxing.


The geothermal heating keeps the water at this temperature year-round, making it a pleasant experience even in colder weather.

What created the Blue Lagoon?

he Blue Lagoon was created as a result of the operations of a nearby geothermal power plant.

1. Geothermal Power Plant: In the late 1970s, the Svartsengi geothermal power plant was constructed to harness geothermal energy from the volcanic activity in the Reykjanes Peninsula. The plant produces electricity and hot water for heating.

2. Wastewater Release: The power plant discharges geothermal wastewater into a nearby lava field. This wastewater, which is rich in minerals like silica and sulfur, initially mixed with natural seawater in the area.

3. Formation of the Lagoon: Over time, the discharged water collected in a natural basin, creating the Blue Lagoon. The lagoon gradually developed into a popular spa destination due to its mineral-rich waters and the soothing experience it provides.

4. Environmental and Tourist Development: The lagoon was officially opened to the public in 1987. Since then, it has been developed into a well-known spa and tourist attraction, with facilities like saunas, steam rooms, and luxury treatments added to enhance the visitor experience.

The unique combination of geothermal activity and mineral-rich waters gives the Blue Lagoon its distinctive appearance and therapeutic properties.
