It was a beautiful morning when we arrived at the Reyjavík city airport for our third flight into the skies above Iceland. Our trips over the Golden Circle and the Westfjords had been outstanding, and today we'd be soaring over Iceland's four biggest glaciers, the Þórsmörk Valley and the Westman Islands.
The 25-kilometer Fimmvörðuháls, or Five-Cairn Trail, leads from the Skógafoss waterfall, up and between two glaciers, and into the valley of Þórsmörk. One of Iceland's most popular hikes, it's often done over two days, with a night in the Fimmvörðuskáli hut, but we pushed ourselves to complete the whole thing at once. Ten amazing hours.
