The Blue Lagoon in Iceland

If you are feeling blue, there is one place in Iceland that will help you wash away the negativity: The Blue Lagoon in Iceland. This man-made natural spa, located near Grindavík, is a renowned outdoor spa in Iceland. This unique attraction captivates both visitors and scientists from all over the world. It is one of the best and most popular things to do in Iceland, and National Geographic even went so far as to claim that it is one of the 25 wonders of the world!


The Blue Lagoon is a man-made wonder, fed by water from Svartsengi geothermal power plant, which heats water vented from beneath a lava field to generate electricity. Originating in 1976 alongside the geothermal plant, the Blue Lagoon was formed from the plant's surplus water, used for extracting steam and hot water, heating the lagoon through natural filtration.

The nearby geothermal plant was using superheated water to power its turbines and provide the region with electricity and heat. The geothermal water source that they were using was huge and contained water that is around 240 °C warm.

When the water had been used for various purposes (power turbines, freshwater heating), it was at a mellow 40 °C and was dispatched some ways from the plant. This dispatched mix of fresh and salty water from the earth’s crust became the Blue Lagoon in Iceland as we know it today.

Research and Wellness

At first, Icelanders viewed this as an ecological crime, but since no nature seemed to be harmed in the process, the power plant was allowed to continue its operation. After a brave man in the neighborhood took a dip in the azure blue waters, he realized that his skin felt better. His friends joined in. Before you knew it, scientists were setting up a lab, running tests and trying to figure out the whole Blue Lagoon Iceland skin care phenomena.

A research- and leisure company was opened in 1992, and at the end of the 90s, the spa was established.

What’s in the Blue Lagoon in Iceland?

Obviously, the water is a striking azure blue, and the contents of the lagoon are somehow good for you. Normally, industrial runoff doesn’t exactly scream “healthy”, but in this case, the runoff water contains plenty of interesting things that are not at all harmful to anyone.

What Makes the Blue Lagoon Blue? The Blueness

In short, the mix of sulfur and silica is the main reason why the water in the lagoon is blue. A nice Blue Lagoon in Iceland fact is that the lagoon is a remarkable ecosystem of algae and microorganisms. These produce the sludge that gives the water a milky look. The color of the minerals and the milkiness from the sludge are the reasons why the Blue Lagoon in Iceland has its characteristic blue, magic color.

The Most Natural Man-Made Facial

It’s well established that the lagoon itself is a man-made pool. The algae and microorganisms in the pool are not, however. These have developed over time and are entirely unique to the Blue Lagoon in Iceland. These are also the things behind the miracle creams, scrubs, and masks at the Blue Lagoon in Iceland.

Facilities at the Blue Lagoon in Iceland

The miracle body of water is surrounded by the Blue Lagoon Iceland hotels and spas. Many hot springs in Iceland are either parts of a larger bathing facility or in nature, with only simple changing rooms nearby. The Iceland hot springs in Blue Lagoon are in a league of their own with all the luxury amenities around them.


Even though the restaurants and hotels are nice to visit, the main attraction is the lagoon itself. The Blue Lagoon main pool is where most people will go on a day out to the Iceland Blue Lagoon resort.

This is where you pay for a dip in the fantastic pool, get a world-class facial, and a drink from the in-pool bar. The Blue Lagoon's maximum depth reaches 1.4 meters (4.7 feet), while its shallowest points are less than 0.8 meters (2.6 feet) deep, so you don’t need to know how to swim to use it. Obviously, non-alcoholic for the youngsters and non-drinking visitors.


Having a dip in the water and applying that magic face mask is already very spa-ish for most of us mere mortals. But if you are looking for more than just a dip in the magic water and a face mask, the Blue Lagoon spa in Iceland is the right choice for you. Going for the “real” spa will give you some options:

Retreat Lagoon

Get a more secluded experience and swim in this separate lagoon. Swim in the canyons and corridors framed by lava rock and enjoy the simple serenity of having your own little Blue Lagoon Iceland tour.

Blue Lagoon Ritual

We promise this isn’t some pagan sacrifice thing. Go through three different chambers in the Blue Lagoon in Iceland and get up close and personal with the silica, algae, and minerals in the healing water.

Lava Cove

Get the spa within a spa. A completely private lagoon (a small one) and a bunch of different amenities will take your experience to the next level. This might be the one part of the facilities where you can make your own Blue Lagoon Iceland nudity policy. In all other places, you are required to wear the appropriate swimwear.


In terms of eating, you can choose between a few restaurants at the Blue Lagoon. These are: the normal café, Spa restaurant, Moss restaurant, and Lava restaurant. The Moss restaurant is recommended by the Michelin guide in 2020. Furthermore, the Lava restaurant is literally carved into an 800-year-old lava cliff. Both are unbeatable experiences.


If you want to stay at the facilities a bit longer, the Blue Lagoon is home to some of the best hotels in Iceland. You can choose to stay at either the Silica Hotel or the Retreat hotel. The Silica hotel is the main hotel that caters to a “normal” hotel stay (as if any of this is of the ordinary). The retreat hotel is aimed towards (you guessed it) a more spa-oriented stay.


The Blue Lagoon Iceland price will depend on what you want to do. The most basic package starts at around ISK 8,500 (~60 USD), and the most luxurious package will go for around ISK 1,270,000 (~9,200 USD)!
