To understand water, you must first understand the Svartsengi geothermal power plant. Located just a few hundred meters from the lagoon, this plant drills deep into the Earth’s crust—approximately 2,000 meters down—where magma heats underground water to extreme temperatures.
For visitors, the precise temperature of the Blue Lagoon is its most critical feature. According to National Geographic , the water cools significantly from its subterranean boiling point by the time it reaches the bathing area, settling into a range that mimics a warm bath. This temperature is ideal for:
Of course, no visit is complete without a trip to the in-water bar, where you can sip a smoothie (the Blueberry and Bilberry is a local legend) or a sparkling wine while your fingertips prune.

This "used" geothermal fluid is what fills the Blue Lagoon. By the time it flows into the man-made lagoon, it has cooled significantly, but it is still standard you need to know: an average of 37°C to 40°C (98.6°F to 104°F) . To understand water, you must first understand the
The in Iceland is often described as an "enchanting" and "other-worldly" geothermal spa [7, 10]. While it is undeniably one of the world's most famous health resorts, it is a man-made phenomenon formed by the run-off from the nearby Svartsengi geothermal power plant [4, 9, 18]. The Experience: Aesthetics & Atmosphere
Superheated water at a temperature of about 240°C (464°F) is vented from holes drilled as deep as 2,000 meters (6,500 feet) underground.
: The power plant uses this water to run turbines for electricity. According to National Geographic , the water cools
: This mineral reflects blue light waves and creates a deep white mud.
The Blue Lagoon Hot is a breathtaking sight to behold. The lagoon's vibrant blue waters are crystal clear, allowing you to see an array of marine life darting about beneath the surface. The water is warm and inviting, making it perfect for swimming, kayaking, or simply wading in the shallows.
