Secret Lagoon

Gamla Laugin, which the operator calls Iceland’s oldest swimming pool, was built in 1891 beside the hot springs at Flúðir, with Litli Geysir erupting a few steps away every few minutes. The springs supply all of the water and replace it every 24 hours with no chemicals, which is why showering without a swimsuit first is mandatory.

About Secret Lagoon

Bathing at Hverahólmi is older than the pool: people washed clothes in the springs, and Flúðir held its local assembly here until 1894. The operator says the first swimming lessons in Iceland were given at Gamla Laugin in 1909, and they ran every year until 1947, when the pool fell out of use for decades. Work to bring it back began in 2005, and it reopened as the Secret Lagoon on 7 June 2014. A walking path circles the pool so you can watch the boiling springs of Vaðmálahver, Básahver and Litli Geysir up close.
