Situated at the head of the Altafjord, it is a lush, green and hospitable shelter in the otherwise cold and windswept Finnmark landscape. Halfway between the grim, barren mountain plateau and the wet, stormy coast, Alta offers tree-clad valleys, pleasant temperatures and no more rain than the Sahara. However at 70 degrees North it is quite a different story in winter, when heavy snowfalls and sub-zero temperatures are the order of the day, and clear dark night skies become the arena for dazzling displays of the elusive Aurora Borealis, also referred to as 'the temperamental lady' by Laplanders. The world’s first Northern Lights Observatory, which played an important role in the development of geophysical and meteorological research during the first half of the 20th century, is located just 12 miles from Alta. Perched atop Haldde Mountain, it towers almost 3,000 feet above Kafjord, where the battleship Tirpitz was based during the Second World War.
