    Did you know?

    Built in 1891, the Secret Lagoon is considered the oldest man-made pool in Iceland. Originally constructed as a public bathing site, it reflects the country's deep-rooted geothermal bathing traditions.

    The Secret Lagoon served as one of Iceland's first outdoor swimming areas, even hosting swimming lessons until the 1940s, helping locals develop essential water safety skills.

    For most of the 20th century, the lagoon remained a local secret, known only to residents of Flúðir as Gamla Laugin (The Old Pool). This obscurity led to its name, the 'Secret Lagoon.' It wasn't until Iceland's tourism boom after 2000 that it became a popular geothermal attraction.

    • For centuries, locals bathed in the warm waters of Hverahólmi, even using nearby hot springs for washing clothes. The site also hosted legislative meetings for Flúðir, the local village, until 1894.
    • In 1909, it became Iceland's first location for official swimming lessons, which continued until 1947, when a new pool opened in Flúðir, leaving the lagoon abandoned.
    • Revived in 2005 and reopened in 2014, the lagoon was restored with modern comforts while preserving its authentic charm, becoming a popular geothermal spot.
