The Blue Lagoon may be the most iconic place you can go in Iceland, and is deservedly a must see! It was our last stop on our way back to the airport, and it was the perfect cap to our entire Icelandic vacation.
Basically, the Blue Lagoon is a humongous hot tub located in the middle of field of lava rock. The spa is heated by lava pushing up from the center of the earth. The milky blue water is not a photographic trick, but is what actually happens when geothermal energy helps heat and enrich the water.
The water is enriched with silica, blue green algae, and mineral salts. These ingredients help clean, exfoliate, nourish, and soften the skin (all while you are relaxing in the heavenly warm water). While soaking, many visitors make silica mud masks to give themselves facials.
We soaked for hours, but unfortunately had to head back to the airport. It was the perfect way to relax after days of trekking around the island, and before a long flight home. Blue Lagoon well worth the money (about $40 USD per person), even if you are passing through Iceland on a layover (the spa is only 20 minutes from the airport).
