Whether you’re a nature lover, a science enthusiast, or a wellness seeker, Deildartunguhver is a must-visit stop on the Silver Circle route, offering both dramatic geothermal displays and relaxing spa experiences.
History of Deildartunguhver
Deildartunguhver’s story stretches back centuries, deeply intertwined with the local community’s daily life and Iceland’s pioneering use of geothermal energy. The spring gushes out water at a staggering 180 liters per second, with temperatures reaching 97°C (207°F), making it the highest-flow hot spring in Europe. Historically, ingenious residents used wooden ducts to channel the hot water to nearby homes, providing heat, hot water, and even steam for cooking—a luxury in rural Iceland.
For nearly 200 years, the land was owned by the same family, with matriarch Sigurbjörg Björnsdóttir renowned for her knowledge of the spring’s healing properties. Eventually, the Icelandic state acquired the land, recognizing its national importance. Today, Deildartunguhver supplies hot water to the towns of Borgarnes (34 km away) and Akranes (64 km away), with pipelines stretching across the region. The spring’s energy also powers nearby greenhouses, enabling the cultivation of vegetables and the rare Struthiopteris fallax fern, Iceland’s only endemic fern.
