Originally built in 1891, the ‘Gamla Laugin’ as it eventually came to be known, was Iceland’s first swimming pool. For decades thereafter, Gamla Laugin was virtually abandoned until its present day owner decided to give it new life in 2005. By this time, the pool had long been forgotten and for a few years he used it as his own private heated swimming pool just for himself and a few friends, remaining a secret for several years. That is how The Secret Lagoon got its enigmatic name.  A natural hot spring feeds the lagoon with 38-39°C water  that bubbles up from deep within the earth at a rate of 10 litres per second, constantly replenishing itself so that there is a steady supply of fresh clean water in the pool at any given time. The Secret Lagoon offers brand new facilities next the hot spring area in Fludir. Facilities available: changing rooms, showers, resting rooms, bar and restaurant area. With the completion of changing rooms, showering facilities, outside deck, walkways and a small café, The Secret Lagoon quietly opened in the summer of 2014.
