The Secret Lagoon, also known as Gamla Laugin, is Iceland's oldest natural swimming pool, dating back to 1891. Located near Flúðir, this unique spot is fed by geothermal hot springs like Vaðmálahver and Litli Geysir, providing warm, sulfur-rich water at a constant temperature of 38-40 degrees Celsius year-round. With a rich history of bathing traditions and a serene atmosphere, the Secret Lagoon offers visitors a relaxing and authentic Icelandic experience in a natural setting.

Secret Lagoon has three pools. This is a great place for families.

Please remember to shower naked prior to getting into the hot springs.
