One of the most significant uses of the heat from Deildartunguhver is for district heating in nearby communities. The water’s high temperature and abundant flow provide a valuable source of geothermal energy for heating homes, businesses, and greenhouses. Most of the water used for central heating in the towns of Akranes and Borgarnes is taken from Deildartunguhver. The hot-water pipeline to Akranes stretches 64 kilometres, which is the longest in Iceland; the water temperature is about 78-80°C when it reaches the town.

It’s safe to visit Deildartunguhver but keep your distance, as you can get splashed with scalding hot water if you get too close. Travellers will see water bubbling up and splashing against moss and rock.

Deildartunguhver is situated in the west of Iceland, near the town of Borgarnes. It’s located within the Borgarfjörður region, which is known for its natural beauty, historical sites, and geothermal activity. Deildartunguhver is located along Route 50, making it relatively easy to access by car. It’s a popular stop for travellers exploring the Borgarfjörður area, which offers a mix of natural and historical attractions.

While Deildartunguhver isn’t a traditional tourist attraction that visitors can swim in (due to its extreme temperature), it’s still a captivating sight. Viewing platforms and paths allow visitors to safely observe the steaming water and steam rising from the spring.

Meanwhile, Barnafossar (Children’s Falls) is a stunning waterfall, wide with water rushing over a rocky landscape creating several cascades. It was named for children who were said to disappear from a local farm and drowned in the river, and lore has it that the mother of the disappeared children cursed the falls and that people should not cross the river. Barnafoss shares the same parking area as Hraunfossar, and it is a short walk to the falls.
