About Nauthólsvík Geothermal Beach
Nauthólsvík is Reykjavík's unique geothermal beach, where the North Atlantic's chill is tamed by heated water. Here, golden sand meets a warm lagoon and inviting hot tubs, creating a beloved urban oasis.
History & Background
Nauthólsvík was conceived and developed between 2000 and 2001, a visionary project aimed at providing Reykjavík residents with an accessible and unique ocean swimming experience. Before its transformation, the area comprised a rugged, natural rocky shoreline, typical of the Icelandic coast. The ambitious plan involved importing vast quantities of golden sand to create the inviting beach we see today, along with the sophisticated installation of a geothermal heating system. This system diverts hot water from the city's geothermal network, mixing it into the lagoon to temper the otherwise icy North Atlantic sea. The beach quickly garnered immense popularity among locals and visitors alike, drawn to its unique blend of warm water and seaside charm. Over the years, Nauthólsvík has undergone several expansions and improvements, enhancing its facilities to include modern changing rooms, dedicated hot tubs, and a steam bath, further cementing its status as a beloved urban oasis and a prime example of Iceland's innovative use of its natural resources.
