Fun Facts About The Blue Lagoon in Iceland

So many people have heard of the Blue Lagoon in Iceland that it’s become something of a cliche.  Why am I writing about it?  Because I am a sheep. baaaa.

No, seriously, it seemed to be the only place that everyone wanted to talk about in my geothermal spas around Iceland post.  Of the approximately half a million visitors that go to Iceland every year, approximately 80% visit The Blue Lagoon. So, if you are going to go, and it seems like most of you are, I’m happy to contribute my two cents.

Tips for Visiting The Blue Lagoon

  • If you have the time, it’s great way to unwind either after you land or before you leave for the airport.  We scheduled a few hours in the afternoon at The Blue Lagoon before boarding our evening flight.  It was a 15 minute drive to the airport.
  • The water has minerals in it that are supposed to make your skin feel great.  On the other hand, it will leave your hair feeling like straw.  Put in lots and lots of conditioner afterwards and it’ll be fine.  Eventually.
  • The lockers are the coolest thing I’ve ever seen.  You wave your locker key over the lock mechanism which isn’t on the locker itself and the mechanism recognises which locker number it is.

  • The line can be long for entry at standard tickets.  Cough up the extra $30 and get the Premium which is a fast entry.  You also get a bathrobe, slippers and a couple of drinks complimentary.  We didn’t pay for Luxury ticket which seems outrageously expensive considering you only get a lounge as an upgrade from the Premium ticket.
  • Children are free.  Teenagers are about half the price of an adult ticket.  On the downside with having children go free is that they don’t get a towel of their own.
  • You can get a Premium ticket drink at the Lagoon-side bar.  I choose a smoothie and my husband had a beer.
  • If you choose not to eat at the Lava Restaurant, there is a cafe with casual seating.
  • If you book early you can get a reservation to have a massage in the Lagoon itself.  We unfortunately got given times which didn’t fit in with our schedule.

  • We thought the food and service at Lava Restaurant was excellent.
  • There are children’s menus available.
  • The restaurant is cool and contemporary with double-height ceilings and floor-to-ceiling windows overlooking the Lagoon.

Fun Facts about The Blue Lagoon

  • There is 6 million litres of geothermal seawater in the pool.
  • The geothermal seawater comes from 6,500 feet/1981 metres below the surface.
  • Underground the water starts off as at 464°F (240°C).
  • The lava field surrounding the Blue Lagoon is 800 years old.

  • The average temperature of the pool water is 100°F (38°C).
  • The seawater contains algae, silica and minerals.
  • The water you are soaking in at The Blue Lagoon is technically waste water from the geothermal power plant that you can see from the Lagoon itself.  Yes, the water is natural but there wasn’t a pool here before some marketing geniuses decided to create one.
  • All you will see are tourists.  People from Iceland tend to use the other geothermal pools that are (ahem!) actually naturally-occurring pools.

General Visitor Information for the Blue Lagoon

Iceland’s biggest tourist attraction is getting even bigger.  In the next year, they are rolling out a hotel so that you can stay nearby.  The airport is so close that it’s effectively an airport hotel.

The deepest The Blue Lagoon gets is 1.6 metres so for adults its standing height.  The floor is natural rock but not slimy like parts of the floor at Myvatn Nature Baths.

Tips for visiting the Blue Lagoon thermal spa in Iceland

Children under the age of 2 are not allowed in the pool.  Children from the ages of 2-8 are required to wear armbands to aid in their flotation.  We saw plenty of kids who did not.

The Blue Lagoon is open daily and requires a reservation.  It is a short drive from Keflavik International Airport and about 40 minutes from Reykjavik.

Enjoy your visit to The Blue Lagoon in Iceland!

  1. Ooh those are some pretty good information! I thought the lake was natural to be honest…not “waste water”!! I’m not so keen on swimming on lakes, you see we have plenty of sea here in Greece so I’ve swam on a lake twice and it was slimey!!

  2. Thanks for all those useful tips. The Blue Lagoon looks like fun. That said, I think I would prefer to visit a natural pool and spend my time among locals. Do you know of one that’s particularly popular?

    1. The Myvatn Nature Baths is another one that is popular but less touristy. Any of the baths I mention in my post, A geothermal spa tour of the Ring Road, tends to be popular with the locals. There are 170 geothermal pools in Iceland so you’ll have your pick.

  3. Although I also want to visit the Blue Lagoon, I laughed very hard when I got to the part where you said the only people we’ll see here are tourists. If I ever make it out to Iceland I’ll have to look for some naturally occurring pools as well!

  4. I know many people talk about the Blue Lagoon, but I loved your post!!
    There are many details I didnt know about! I do understand why people wanna go there, I do too 😀
