Everything you need to know about the Blue Lagoon

A popular feature on nearly everyone’s bucket list is the inviting warm waters of Iceland’s Blue Lagoon. The waters of this geothermal spa are made up of silica, algae and minerals, and it is the sunlight reflecting of this silica that gives the lagoon its famous milky blue colour.


The lagoon is man-made and is full of the excess water from the adjacent geothermal power plant. As a result the temperature of the water is around 37- 40°c. The algae present in the water are thought to have fantastic benefits on the skin and there is a silica bar where you can slather a mud mask onto your face. It leaves your skin feeling amazingly soft afterwards! And whilst you are relaxing there will be plenty of time to take in the surrounding dramatic scenery consisting of towering black rocks which has been shaped by the flow of lava.


There are plenty of changing facilities inside the spa and I would definitely recommend bringing lots of layers for when you are ready to depart, climbing out of the spa will leave you feeling noticeably colder. Despite having read many things about the minerals damaging your hair, I found that this was definitely not the case; however it can make your hair slightly dry so I would take plenty of conditioner with you.


My last few tips for the Blue Lagoon is that it is extremely popular and therefore gets very busy so you absolutely need to book in advance. The Lagoon is also very close to Keflavík airport (about a 20 minute drive) so it might be easier to visit right at the start or end of your trip.
