History of Gamla Laugin Flúðum

The Secret Lagoon, or more precisely Gamla Laugin, which means the Old Pool in English, was constructed in 1891 long before Iceland became the popular tourist destination of today. It served as a local swimming spot for the people of Flúðir, offering them a natural way to bathe in geothermal water. Over the years, it became less and less visited until it was rediscovered and remade into what we know today as the Secret Lagoon. The renovations preserved the authenticity of the lagoon and, at the same time, made it more accessible and friendly for tourists. The original changing facilities still stand, blending modern comfort with historical charm, making it both a relaxing and culturally rich experience with a glimpse of what it used to be.

Formation and Geology

The Secret Lagoon is located in the geothermal area of Flúðir, where natural underground heat rises to the surface, creating natural hot springs. The water feeds from a nearby hot spring, which is renewed constantly by fresh water, so keeping the lagoon refreshing and clean. The surrounding area also contains a number of bubbling hot springs and a very small geyser, further adding to its geological interest. The reason for this geothermal activity in Iceland, where both volcanic and geothermal activities are in their most vivid manifestation, is this unique positioning between the Eurasian and North American tectonic plates.
