Iceland's geothermal activity means that there are tons of natural hot pools all over the country. Some are marketed as tourist destinations (like the Mývatn Nature Baths or the Secret Lagoon in Fludir), while others are truly natural and usually just stumbled upon or found by people in-the-know. There's also the famous Blue Lagoon, of course, but this one isn't actually a natural hot spring! It's a man-made spa and hot pool fed by runoff from a nearby geothermal plant and worth the visit.

Blue Lagoon Spa – This mineral-rich attraction is minutes from the Keflavik International airport. There are many spa options available due to the geothermic forces and many natural elements. It’s an incredible source of healing for people with psoriasis. The lagoon is human-made and renewed every two days with fresh water. The geothermal water in the Blue Lagoon is an incredible resource and people from around the world come for not only the bucket list experience but the relief they feel from these special waters. You can easily access the site via car or bus.
