Bird’s eye view of Deildartunguhver hot spring in Iceland

Iceland is well-known for its geothermal activity, with an abundance of hot springs scattered across the land. The country’s location on the Mid-Atlantic Ridge means that volcanic and tectonic activity is at a high, resulting in bubbling hot springs varying in size and characteristics. Not only do the hot springs present unrivalled photo opportunities for adventurous visitors, but they are also used as energy sources to heat water for swimming pools, greenhouses and nearby homes.

We’re sure you’ve heard of some of the most famous hot springs in Iceland including world-renowned tourist locations such as Blue Lagoon, Reykjadalur and the Secret Lagoon. But have you ever heard of Deildartunguhver? 

Located in western Iceland, this major hot spring should definitely be added to your Iceland itinerary. Discover everything you need to know about Deildartunguhver, including things to do and what you can expect when visiting there.


What is Deildartunguhver?

Deildartunguhver is the most powerful hot spring in Europe, with a flow rate of roughly 180 litres per second and a temperature of around 97°C. Sitting in Reykholtsdalur, a district of West Iceland, the hot spring has many uses, and can be used to heat homes and greenhouses, as well as local pools.

Uses of Deildartunguhver

Much of the hot water from the spring is used for heating homes in the surrounding area. The water from Deildartunguhver is piped to the two nearby towns of Borgarnes and Akranes, which are located 34 and 64 kilometres respectively away from the spring. This means that if you have taken a shower or bath within a 64-kilometre radius of Deildartunguhver, you would have likely used water from the hot spring itself!

Iceland is well-known for its efficient use of geothermal energy, and hot springs play a significant role in enabling this. Most of the hot water in Iceland is sourced from hot springs, with the exception of some parts of the country, such as the Westfjords. This is because the lands are geologically older, and therefore less active. Iceland’s geothermal activity is considered why the country has such a good reputation for green energy and sustainable practices.
