The Blue Lagoon: What to Know Before You Go

The Blue Lagoon: What to Know Before You Go

Posted January 24, 2017

The Blue Lagoon is a must-have experience for many travelers visiting the country.  Nestled amidst Iceland’s natural landscape, the Blue Lagoon is a geo-thermal spa with water temperatures remaining between 98-104°F year-round.  The milky-blue hued water is a mixture of both underground geo-thermal water and fresh water originating more than 6,000 feet below the surface. On the way to the surface, the water picks up silica and minerals.  The water is even self-cleansing – renewing itself every 40 hours.  

The Blue Lagoon is a relaxing and fun experience, but there are a few things you should know before you go.

Pack a Towel, Flip Flops, and Plastic Bag

After entering the lagoon facility, you will pass through the locker rooms to store your backpacks and clothing.  Then before hopping into the lagoon it is required that you take a shower.  However, we recommend using the towel and flip flops for the post-lagoon shower (shower gel and shampoo can be found inside the stalls so don't pack these items) before changing back into your regular clothes. During your time in the lagoon a towel isn’t necessary as you are just a few steps from the locker rooms. If you prefer not to pack towels and flip flops, these items are available for rent.  A plastic bag will also be helpful for storing a wet bathing suit. 

Don’t Get Your Hair Wet

The silica in the water can wreak havoc on your hair – making it dry, brittle, and difficult to manage.  We recommend that women tie hair up off their shoulders.  However, the lagoon isn’t very deep so keeping your hair dry is not a problem while walking through the water.  The shallowest point is almost two feet while the deepest is five feet.

Don’t Wear Jewelry

It is best not to wear jewelry in the water as the silica, algae, minerals can accumulate in the jewelry and be difficult to remove.  Either lock jewelry in your locker or keep it in the hotel safe.

Drink Water

As the temperature is very warm, it is recommended to drink water before, during, and after your soak in the Blue Lagoon.  There is a swim up bar where you can order drinks.  Please note:  as you redeem your tickets at the entrance you are handed a bracelet that will link to your credit card.  You can purchase drinks at the bar with your bracelet.  Store your wallet in your locker.

Wear Sunglasses

The color of the water can range from white to blue to green depending on the sun.  Since the water is opaque, the water reflects sunlight even on cloudy days. A pair of sunglasses will make your soak more comfortable.
