So seriously, for those who’d like to see the Blue Lagoon but don’t feel like paying € 50+5 fee, there’s a small secret tip.
When you face the entrance of Blue Lagoon’s building, there’s a path on your left (not this picture above…. to its left). Walk along that path and you’d see the magical blue spring. It looks pretty amazing to me! I touched it and it was cold. Still pretty cool!
It’s basically at the back of Blue Lagoon… so I think it’s the same wasted water from the geothermal power plant without being heated up.
The lagoon is a man-made lagoon which is fed by the water output of the nearby geothermal power plant Svartsengi and is renewed every two days. Superheated water is vented from the ground near a lava flow and used to run turbines that generate electricity. After going through the turbines, the steam and hot water passes through a heat exchanger to provide heat for a municipal water heating system. Then the water is fed into the lagoon for recreational and medicinal users to bathe in. (Wikipedia)
Still looks pretty blue to me. Although it might look better on a sunny day!
The water is said to have rich minerals.
On the other hand, it might work out to be a good deal for you if you like the Blue Lagoon and stay at their accommodation, the Clinic Hotel. At €300 for a double room in summer, it includes a night’s accommodation, breakfast, private lagoon, and entrance to Blue Lagoon. http://www.bluelagoon.com/blue-lagoon-spa/accommodation/
