October 28, 2025, Nauthólsvík Geothermal Beach

Due to the inflow of warm water from geothermal springs, the bathing temperature in the bay is comparatively pleasant.

Located just minutes from the city center, this domestic airport connects the capital with other regions of Iceland and Greenland. It should not be confused with Keflavík International Airport, which handles most international flights. Routes to Akureyri, Ísafjörður, and Egilsstaðir depart from here, providing a quick way to shorten distances on the island.

Reykjavík Airport (Icelandic: Reykjavíkurflugvöllur, IATA code: RKV, ICAO code: BIRK) is the domestic airport serving the Icelandic capital, Reykjavík. It is located in close proximity to the city, which borders it to the north and east. To the south lies the sea, and to the east the recreational area of Öskjuhlíð. International flights (except those to Greenland) are handled by Keflavík Airport, located 50 km away.

Located in the Lautholsvík district, roughly west of Reykjavik, the beach is known for its impressive scenery and unique water. What makes this beach so special is its proximity to geothermal springs, which heat the water to a pleasant temperature. The water is often warm, making Lautholsvík Beach a popular spot for locals and visitors alike who want to enjoy a relaxing swim in warm water, even when the weather is cool outside. The beach itself consists of black sand and small pebbles, which is typical of many Icelandic beaches. The surroundings are wild and untouched, with impressive cliffs and breathtaking views of the Atlantic Ocean. The nature here is rugged and beautiful, perfect for nature lovers and photographers.

The shipwreck is clearly visible from the lookout point. It's not recommended to climb down to avoid damaging the coastline.

If you prefer to walk, there are various hiking trails leading up to the Perlan Museum. The entrance fee of €36.00 is well worth it - a great museum. There is also a restaurant in the museum, and food is available until 6 p.m.

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.
