Secret Lagoon

The Secret Lagoon is a large oval geothermal pool in Iceland that maintains warm water year-round from natural heat sources. It receives fresh water continuously from several hot springs, including an active geyser that keeps the pool supplied and at comfortable bathing temperatures.

This pool was established in 1891 as Iceland's first swimming facility, marking a turning point for recreational bathing in the country. The first organized swimming lessons in Iceland took place here starting in 1909, continuing for many years.

For local people, this geothermal pool was more than a bathing spot - it served as a gathering place for washing clothes and holding community meetings. This shared use shows how central the warm water was to everyday life in the area.

The location has separate changing rooms, showers, and a small bistro for refreshments to serve visitors comfortably. Opening hours vary by season, with extended hours available during the warmer months.

The site is home to Litli Geysir, a small active geyser that continuously shoots water directly into the pool, naturally refreshing it. This active geothermal feature gives visitors a close view of Iceland's raw natural forces at work.
