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.
As amazing as it was to stand on the cliffs of Þingvellir and survey the rift valley where two tectonic plates are separating, it was even more amazing to fly over that same valley. I think I know why so many birds spend their summers in Iceland. The views are hard to beat.
