Hidden golden sand beach in Reykjavik warmed by geothermal water, tucked between Öskjuhlíð hill and the sea. Free entry, outdoor hot tub, and a lagoon heated to 15-19°C. Locals flock here in summer but tourists rarely find it.
Nauthólsvík is a small artificial beach in Reykjavik, tucked into a cove between Öskjuhlíð hill, home to the Perlan museum, and the sea, where imported golden sand and geothermal water piped into a shallow lagoon create a swimmable beach despite Iceland's cold climate. The lagoon itself is heated to around 15-19°C, considerably warmer than the surrounding Atlantic, and an adjoining hot tub reaches typical spa temperatures for those who want more direct warmth. Because it operates as a municipal facility rather than a commercial spa, entry is free, and the site draws mostly local residents rather than tour groups, giving it a distinctly different, low-key atmosphere compared to Iceland's paid geothermal attractions. Changing rooms, showers, and lifeguards are on site during operating hours, which are shorter in winter, and the beach is at its most popular on warm, sunny days in June through August when locals treat it as a genuine summer swimming spot. The Perlan museum sits directly on the hill above, making it an easy pairing for a half-day combining indoor exhibits with an outdoor geothermal swim. A visit for a soak and some beach time takes about one to two hours.
