Deildartunguhver

Deildartunguhver thermal spring is the largest thermal spring in Iceland. It provides 180 l/sec of 100°C hot water. Some of the water is harnessed for heating utilities in Akranes (64 km) and Borgarnes (34 km), and for farms along the way. A variety of hard fern (blechnun spicant) can be seen near the thermal spring, which does not grow anywhere else in Iceland. The thermal spring is protected. Greenhouse farming is extensive in Deildartunga as well as in other places in the neighbourhood.
