Continental Europe's largest ice cap is here. Ditto its highest and largest plateau. And the world's longest ice-free fjord, northern Europe's highest peak plus four of the world's highest waterfalls. You get the picture – or hundreds of them. Norway vacations are a geo-blockbuster, laced with colourful myths (all those trolls...) and strange lights which float magically around valleys that may just be remarkable 'natural batteries'.
