37 kilometres outside the town of Borgarnes sits the great Deildartunguhver, Europe's most powerful hot spring. This impressive natural feature is characterised by its very high flow rate (180 litres per second) and its toasty 100-degree water temperature.

The spring is crucial to the surrounding area, operating as the central heating provider to the nearby towns or Borgarnes and Akranes; it is said that any shower within a 65km radius of the spring will be powered by the water from Deildartunguhver. When you're visiting this sight, keep any eye out for the Blechnum spicant, a fern that is nicknamed 'deer fern' or 'hard fern'. The plant is abundant in the region but rare to the rest of Iceland due to its need for warm, humid growing conditions.

There is plenty of accommodation and activities in the area, for instance there are 18 hole golf courses in both Akranes and Borgarnes.
