Opaque blue-white water in a field of black lava. Nothing else looks like this.
The Blue Lagoon's signature color — a milky, luminous blue-white — comes from silica nanoparticles suspended in the geothermal water, scattering light the same way Earth's atmosphere makes the sky blue. The water itself is a byproduct of the Svartsengi power plant, which extracts geothermal energy from deep in the earth and discharges the mineral-rich water into the lava field. The silica and sulfur concentrations have documented therapeutic effects on psoriasis and eczema.

An insider's tip
The 7am slot has the most dramatic steam in cold morning air. Bring a hair tie — silica tangles and dries hair badly.
Don't leave without
Apply the white silica mud mask from the in-water dispensers. Leave it for 15 minutes. Your skin will be noticeably different afterward.
