While in the Reykholt area, it’s well worth checking out the biggest hot spring in Europe, Deildartunguhver, which lies near the hamlet of Kleppjárnsreykir, 5km west of Reykholt on the side of Route 50. Drawing on the geothermal reserves that lie all around Reykholtsdalur valley, and pumping out a staggering 180 litres of 97°C water a second, the billowing clouds of steam created by this mighty fissure are truly impressive, reaching up high into the cool air – in fact it’s water from here that runs via two specially constructed pipelines to heat Borgarnes and Akranes, 34km and 64km away, respectively. As in so many other geothermal areas around Iceland, water from the spring is also used to speed up the growth of plants and vegetables by heating up the surrounding greenhouses, and during the summer local farmers often set up stalls here to sell their produce to passing visitors. From the car park, a footpath leads to the spring.
