Blue Lagoon vs Sky Lagoon

The famous Blue Lagoon or the new Sky Lagoon?

Iceland was blessed with geothermal water which is a natural wonder that it can be used for producing energy, for pools, and even for baking. The Vikings used geothermal water mostly for geothermal baths so bathing in geothermal pools is strongly connected with Icelandic culture.

Geothermal pools look different now than they used to be but this may be a good thing. There are many geothermal pools in Iceland that offer now an entire spa experience using the natural resource.

Blue Lagoon is the most famous geothermal spa in Iceland and it is famous worldwide not only inside the country. Its blue water and the silica masks are convincing tourists all over the world to stop there first when they come to Iceland. Blue Lagoon was opened in 1987 so it has a tradition in Iceland.

Sky Lagoon is a newly open geothermal bath. Located just a few minutes away from downtown Reykjavik, Sky Lagoon is offering a stunning view over the ocean as the concept was to create a pool that will give the illusion of an infinity pool. The concept behind the Sky Lagoon was to recreate a truly Viking bathing experience.

Can those two geothermal baths even compete? Let’s find out what to expect from each geothermal pool.

The water is BLUE! Why? Because the water contains a natural mineral called Silica which reflects light making the water look blue. In fact, the water is cloudy white in color.

The water is very good for the skin. Yes. This natural silica mineral in the water is very good for the skin. It is an ingredient found in spa products like face masks and moisturizers. Spend some time in the waters at the Blue Lagoon and you will feel that your skin is significantly smoother and nourished.

The water at Blue Lagoon is salty. Yes, it is. The reason being is that due to the location of the geothermal water source of Blue Lagoon being relatively close to the ocean, small amounts of seawater seep through the lava rocks into the geothermal water source, causing the water to be slightly salty. This, in fact, makes the water even better for the skin. On top of being natural geothermal water with natural silica minerals, it also has some natural minerals from the ocean.

The water at Blue Lagoon is wastewater. In a way of saying, yes, but the context is that the geothermal power plant right next to Blue Lagoon uses the geothermal water to generate electricity first before the water flows into Blue Lagoon. This process simply removes some heat from the boiling geothermal water so that the water temperature is suitable for you and me to soak in. Nothing else is done to the water. In a way, the water is used in a more effective way, saving the environment.

At the Blue Lagoon, children 13 and under enjoy free admission. The age limit for entering the water is 2 years. Free admission for children means no additional services and they will share a locker with their parents.

Blue Lagoon has also accommodation facilities so you can stay there overnight and enjoy a whole day there.

Sky Lagoon is newly open this year and came out with a new concept of a geothermal pool made near the ocean so you can immerse yourself in the hot geothermal water and breathe the ocean air.

The water in Sky Lagoon is natural geothermal water that contains minerals that can detoxify and can help remedy skin ailments.

The concept of Sky Lagoon came out with a 7 step ritual for the skin. The ritual starts with your way from the changing room to the infinity pool outside. All you need to do is to step into the warm water of the lagoon and relax.

The second step is typically Icelandic: a deep into the cold water. This step is a traditional Viking way to stimulate the immune system, decrease the blood flow into the body, and tighten the skin. This step is not mandatory but if you are brave enough you can do it (don’t stay more than 10 seconds).

The third step includes a visit to the sauna. Sky Lagoon has a nice sauna with a glass wall that will let you enjoy the scenery while you allow the heat to open your pores, remove toxins and cleanse your skin.

The fourth step is about refreshing your senses by stepping into the fog mist area.

For the next step, you will use Sky Lagoon signature Sky Body Scrub. The scrub is made of sea salt, with a spring-like scent that will gently exfoliate your skin.

After spoiling yourself with the Sky Body Scrub, the sixth step is a visit to the steam room. The steam will help your skin absorb the benefits of the scrub.

The final step is going back to the pool to relax and enjoy the whole journey. After you shower, you can let the geothermal water take care of your skin and body.

At Sky Lagoon the age limit is 12 years.
