Just outside the hot spring haven of Hveragerði is the Hellisheiði Geothermal Power Station. If you want to visit, don’t worry about accidentally driving past without spotting it. This is the world’s largest geothermal plant, spouting giant columns of steam high into the atmosphere, and it’s unmistakable.
The first half of our 25-kilometer hike from Skógar to Þórsmörk had been dominated by waterfalls, barren mountain vistas, and an unending uphill climb. But after passing between the two glaciers of Eyjafjallajökull and Mýrdalsjökull, our path would start its descent, and the clouds which had been plaguing us all day would clear up, revealing the valley of Þórsmörk below us: one of the most stunning landscapes we’ve ever seen.
