Book NowStory & Folklore
Deildartunguhver is Europe's highest-flow hot spring — producing 180 litres of 97°C water per second from the earth. The spring is located in Borgarfjörður in West Iceland and has been used as a district heating source for over a century; today, hot water is piped 74 kilometres to Akranes and 64 kilometres to Borgarnes — one of the world's longest hot water pipelines. The spring itself is dramatic: enormous volumes of near-boiling water burst from the ground in constant clouds of steam. Covered viewing platforms allow close inspection. The adjacent Krauma spa uses the same water, cooled to bathing temperature. Deildartunguhver is a stop on virtually every West Iceland driving route.
