About Deildartunguhver
Deildartunguhver is one of Iceland’s most powerful hot springs and an incredible natural wonder located near the village of Reykholt in West Iceland. It holds the title of Europe’s most voluminous hot spring, pumping out around 180 liters of boiling water per second at a constant temperature of 97°C.
The spring is a fascinating example of Iceland’s geothermal activity, where water heated deep underground emerges to the surface in clouds of steam and vibrant colors. The surrounding landscape is painted in red, green, and orange tones due to minerals and heat-loving algae.
Deildartunguhver isn’t just impressive to look at, it’s also essential for local life. Its hot water is used to heat homes in nearby towns such as Borgarnes and Akranes through Iceland’s extensive geothermal pipeline system.
The Landscape and Geology
Deildartunguhver sits on a geothermal field that marks the boundary between lava and sedimentary rock formations in Borgarfjörður valley. The intense underground heat comes from water that has seeped deep into the earth, where it is naturally heated by volcanic activity before returning to the surface through cracks and vents.
The spring itself is not a single geyser but a cluster of steaming vents and bubbling pools stretching across a small hillside. Wooden walkways and barriers have been built for visitors to safely observe the boiling water and colorful earth without risking burns.
The red hue of the soil and rocks around the spring is caused by iron deposits, while the green and yellow streaks come from thermophilic algae that thrive in the extreme heat. These colors, combined with the constant billows of steam, create an otherworldly scene, especially on cold or rainy days when the contrast is strongest.
