The history of Nauthólsvík is as fascinating as its current appearance. Where today golden sand lines the shore and warm, geothermal water invites you to linger, the Nauthóll farm once stood, which was destroyed by a tragic fire during a typhus epidemic. During the Second World War, this area served as a landing site for amphibious aircraft and over the decades has found its importance as a summer excursion destination. However, the area changed over time and the warm water that once flowed naturally into the bay became blocked. But the people of Reykjavík were not discouraged. With a vision in mind to breathe new life into this place, the bank was redesigned towards the end of the 90s. Mighty rock walls protect the bay today, while fine yellow sand covers the bottom. What’s special about Nauthólsvík? Despite Iceland's typically cool sea temperatures, the lagoon offers a pleasant swim at 15-19° C in the summer months thanks to the hot water tank drain from Öskjuhlíð. And the city's passionate sea swimmers? You don't let the cold or wind stop you and enjoy a refreshing swim every day. Open your book and sit on the sand as the gentle waves of the geothermally heated lagoon roll onto the shore. Families will find a paradise here: shallow pools for the little ones and the warming sauna to relax after swimming. At low tide there is even another round pool that partially sinks under water and invites you to explore. The proximity to the center of Reykjavík makes Nauthólsvík an easily accessible destination, be it on foot or by car. And best of all: entry is free. There is only a small fee for lockers.
