Your wristband
Upon your arrival, you will be given a wristband which has multiple uses. This colorful item is the key to your changing room locker. But it also functions as an in-water credit card. You can use it to purchase drinks and refreshments anywhere in the spa area.
Your locker and changing rooms
You will receive a private locker. We recommend that you store all your valuables—jewellery, shoes, cameras, etc. inside your locker. But be sure to check that your locker is properly locked before you walk away. Blue Lagoon is not responsible for any lost valuables. There are separate changing rooms—equipped with showers and electronic lockers—for men and women. Our facilities include dedicated changing rooms for women, men, and a gender-neutral space, ensuring comfort and privacy for everyone. If you would like more info about our changing rooms and our changing room policies, please contact us.
Use hair conditioner
The seawater in the Blue Lagoon has high levels of silica. Silica is not harmful to hair. However, if your hair gets wet, it can become stiff and difficult to manage. Therefore, we recommend that you apply conditioner to your hair before entering the lagoon--and leave it in your hair while in the lagoon. Complimentary conditioner is provided in the shower area.
Drink water and stay hydrated
You can become dehydrated in hot water. Therefore, we highly recommend that you drink plenty of water during your visit to the Blue Lagoon. This is particularly important for people who have diabetes or high blood pressure.
Prescription eyeglasses
If you have prescription eyeglasses and choose to wear them in the Blue Lagoon, be sure not to submerge them in the water. Silica—one of the Blue Lagoon's geothermal treasures—can damage the lenses.
Contact lenses
Salt, minerals, and other elements found in the seawater of the Blue Lagoon can irritate your eyes. Therefore, if you wear contact lenses, we recommend that you remove them before entering the lagoon.
Children at Blue Lagoon
The Blue Lagoon has a minimum age limit of 2 years old. Children aged 2-to-11 are welcome to enjoy the Blue Lagoon with their family or guardian. However it is mandatory for children aged 2 to 8 to wear inflatable armbands (aka, ‘floaties’, ‘water wings’) in the lagoon. These are provided free of charge. Also be aware that each guardian is only allowed to supervise two children under the age of 10. For safety, and out of respect for other guests, please keep an eye on your children at all times. Entry fee for children 11 and younger is 2000 ISK
Phones at Blue Lagoon
Phones are permitted in the Blue Lagoon Spa; however, we advise using caution while in the water and recommend protecting your device with a waterproof case. Waterproof cases are available for purchase at our facility. Please be mindful and respectful of other guests during your visit.
