Geothermal Beach of Nauthólsvík

Nauthólsvík, located a few kilometers from the center of Reykjavík, is a unique geothermal beach, a hidden gem that offers an unusual bathing experience in the harsh Icelandic climate. Inaugurated in 2000, this artificial beach was created to harness Iceland’s geothermal resources, transforming a corner of the northern Atlantic Ocean into a cozy bay with warm waters, golden sand, and modern leisure facilities. The beach of Nauthólsvík is a perfect example of how Icelanders have been able to use their exceptional natural resource, geothermal energy, to improve quality of life and create innovative recreational spaces. The geothermal lagoon is powered by warm water pumped from nearby geothermal wells, mixed with cold seawater to reach a comfortable temperature that can vary between 15 and 20 degrees Celsius, depending on weather conditions. This mixture creates a surprising and pleasant contrast with the external temperatures, which can be very low, especially during winter. Historically, the Nauthólsvík area was used for bathing since the early decades of the 20th century, but it was only with the construction of the current geothermal facilities that it gained the popularity it enjoys today. The opening of the geothermal beach marked an important moment in Reykjavík’s recreational infrastructure history, demonstrating the city’s commitment to promoting healthy and sustainable lifestyles through innovative use of natural resources. The environment of Nauthólsvík is designed to offer a relaxing and rejuvenating experience. The beach is equipped with changing rooms, showers, and a café serving hot drinks and snacks. For those seeking a bit more adventure, there is also a geothermal hot tub and a steam bath, offering additional opportunities to relax and enjoy the natural warmth while admiring the surrounding landscape. In addition to the geothermal lagoon, Nauthólsvík also offers a wide sandy beach, a rare and precious element in Iceland, where beaches are often composed of volcanic black sand. The golden sand has been imported to create a more familiar environment for visitors who want to sunbathe, play on the beach, or take a walk along the shore. This combination of golden sand and warm waters makes Nauthólsvík an extraordinary, almost surreal place, where the Nordic climate meets a Mediterranean beach atmosphere. An interesting anecdote concerns Nauthólsvík’s participation in the annual cold water swimming competition. Every year, swimmers challenge themselves in the icy waters of the northern Atlantic, showcasing not only their physical endurance but also their adventurous spirit. These events attract participants and spectators from around the world, helping to promote the geothermal beach as a premier destination for cold water swimming.
