Known as the ‘midnight sun’, places above the Arctic Circle, including Greenland’s northernmost towns, do not see any darkness from late April to late August. Skies still shift and shimmer, smearing stark white daylight into golden evening hues, but the sun remains ever-present, creating the impression of perpetual un-ending daytime. Hiking at this time is especially spectacular – empty trails with hardly another soul in site are lit by a beautiful, eerie light. Come mid-November, though, and the sun packs up completely and the lights go out, leaving behind a long, dark winter where the skies come ablaze with the magnificent Aurora Borealis.
