Nauthólsvík is Reykjavík's managed geothermal beach, where city hot water feeds two hot tubs and mixes with seawater in a partly sheltered sandy bay. It is a local bathing place, not a natural hot spring or resort lagoon.
Bathing details
Nauthólsvík combines a sandy public beach with geothermal bathing, but the hot tubs and the seawater bay are not the same experience.
Hot water from Reykjavík's supply flows into two hot tubs and into a bay partly enclosed by a seawall. The seawall limits water exchange, but the bay remains open to the fjord, so tides still move through it and hot water mixes with cold seawater. The beach is managed infrastructure rather than a naturally heated cove.
Golden shell sand, changing facilities and the sheltered shape make the site feel more like an urban bathing area than Reykjavík's ordinary shoreline. The beach opened on 17 June 2000 as a place for outdoor recreation, sunbathing and sea swimming.

Photo guide
A busy summer scene shows why the beach is a local Reykjavík bathing stop, not wild coast.
The hot-water bathing area provides the predictable warmth, while the bay changes with tide, season and weather.
On a calm summer day, the sand and shallow sheltered water can support a relaxed beach visit. In colder weather, the same place is used more deliberately by sea swimmers who return to the hot water and changing facilities. Do not assume that the whole bay will feel warm because the site is called geothermal.
Cold-water swimming brings risks that a normal hot tub does not. Enter according to your experience, follow staff instructions and posted notices, supervise children closely and leave the water if conditions or cold become uncomfortable.
Nauthólsvík is outdoors, but use of its staffed changing, shower and bathing facilities follows a service schedule.
Hours differ between summer and winter and can change around holidays. Fees and pass arrangements also change, so this guide does not repeat figures that may soon be stale. Check the city's live page before relying on showers, changing rooms, hot tubs or other services.
Bring swimwear and a towel. Reykjavík's bathing guidance tells visitors to shower thoroughly without swimwear before entering managed pools; follow the instructions posted at Nauthólsvík.

The beach is strongest as a flexible Reykjavík activity rather than a substitute for a large commercial lagoon.
Choose Nauthólsvík for sea air, sand and a community bathing atmosphere. Sundhöllin is the clearer city choice for lap swimming and a more conventional pool setup. Sky Lagoon and Blue Lagoon are separate paid destination experiences with a different scale and purpose.
A short look at the beach can take minutes, but a proper bathing visit should not be rushed.
Allow roughly one to two hours when you plan to change, shower, bathe and warm up comfortably. In good weather, the sand and surrounding paths can extend the stay; in wind or cold, the facility itself may be the whole visit.
Perlan is nearby on Öskjuhlíð and offers an indoor Reykjavík contrast. Pairing the two can make sense geographically, but Nauthólsvík should remain a weather-led choice rather than a fixed obligation.
