In summer the green valley of Þórsmörk, ringed by glaciers, is one of Iceland's busiest highland spots. In winter, when the mountain F-roads close and the rivers run high with meltwater and ice, it becomes almost impossible to reach — and utterly deserted.
Getting in means a specialist super-jeep that fords icy rivers, and then travelling on snowshoes across ground no wheel can cross. The reward is the highlands at their most elemental: snow-laden birch woods, frozen waterfalls, glacier snouts and total silence, with the short winter light turning everything pink and gold.
It is a rare, effortful way to see a landscape that most people only ever experience in the crowded warmth of July, and the sense of having it entirely to yourself is the whole point.
