Deildartunguhver

Deildartunguhver is a mighty thermal spring at the mouth of the Reykholtsdalur valley in West Iceland. Here you can experience the geothermal forces at work underneath Iceland’s bedrock for yourself.

Hot water rushes out of the spring at a flow rate of 180 liters per second, the highest of any hot spring in Europe. When the water reaches the ground, it’s at a temperature of 97°C (206°F).

Deildartunguhver is located inland, and is just a 20-minute drive from the waterfalls Hraunfossar and Barnafoss. Around the hot spring you’ll see greenhouses where tomatoes are grown using the heat generated.

The hot spring is within a geologically active belt that stretches from the Reykjanes peninsula in southwest Iceland to the north. This geological activity is what heats the water of the Blue Lagoon and the Strokkur geyser in the Geysir geothermal area.

Hot water from Deildartunguhver is used to feed the neighboring Krauma Geothermal Baths. Here you’re treated to a stunning view of the surrounding valley in the comfort of a pleasantly warm pool.
