The Blue Lagoon is a must-see if you’re visiting Iceland; here are 5 things you should know about it before you go:

1. Geothermal Power

Iceland is a tiny island nation located in the north Atlantic, parallel to Greenland and between North America and Europe. The island was formed by volcanic forces and there are still active volcanoes today. That means that Iceland has abundant geothermal energy, which the nation uses to power pretty much everything. The Blue Lagoon is actually a result of those two features: the volcanic formation and the use of geothermal power - coming together.


2. Minerals in the Water

Iceland’s volcanic nature means that some minerals and elements occur more frequently in the soil. Volcanic ash spewed out of the volcanoes and the presence of lava contributes to high incident rates of some minerals. The water that passes through the geothermal power plant and then flows into the Blue Lagoon is also heavily mineralized; it contains high concentrates of silica, which is what gives the water its characteristic milky-blue color.

3. Healing Properties

When the Svartsengi power plant opened the retaining pond that would become the Blue Lagoon in 1976, nobody envisioned it becoming the major tourist attraction it is today. Word soon got round, however, that the water in the “lagoon” had medicinal properties for people suffering from skin diseases such as psoriasis. Since the water is rich in minerals like silica and sulfur, people still maintain that the water of the Blue Lagoon has medicinal properties, even for people who aren’t suffering from skin ailments.

4. Iceland’s Most Visited

Despite not even having been around for a quarter-century yet, the Blue Lagoon spa has emerged as Iceland’s most visited attraction. It’s hard to say which came first: increasing tourism to Iceland, which then resulted in the popularity of the Blue Lagoon, or the Blue Lagoon being revered as a place to visit, thus resulting in a boom in Iceland tourism.

5. It’s Beautiful

In the evening the Lagoon takes on ethereal colors as the sun goes down, lights reflecting on the water’s surface and the sky mirroring the surface of the water (or perhaps vice versa). It’s not hard to see why people would flock here, medicinal benefits or no, when the landscape is just another testament to why Iceland is an amazing place to explore.
