The most powerful hot spring in Europe

Situated on a beautiful farm, Deildartunguhver is the most powerful hot spring in Europe with a flow rate of 180 litres (50 gallons) of water per second at a piping hot 97°C (200°F). The scalding water rushes out of an algae covered rocky outcrop.

In addition, a fern called the “deer fern” or “hard fern” grows near Deildartunguhver. This fern grows nowhere else in Iceland.

Above all, if you take a shower anywhere within a 65 km radius of this powerful hot spring, you have already bathed in its water!
