Booking is easy online through each operator's own website or via Entur, Norway's official national transit planner and public transport travel planner covering every operator in one place. Advance-purchase tickets can cut prices significantly if you book train tickets a few weeks ahead, though the cheapest tickets — often low fare tickets — are usually non-refundable. An Interrail or Eurail pass — useful if you're planning multiple journeys — covers most routes too, since Norway sits inside the wider European rail network. Choose your route, then book directly: connecting buses cover the fjord villages the railway doesn't reach.
For many travellers, this is a once-in-a-lifetime adventure: a genuinely enjoyable way to see a country built on fjords and mountains, from the North Sea to the Arctic Circle. Few rail journeys anywhere in the world cover this much dramatic ground in so few hours. Whether you're travelling with friends, family, or alone, the comfort of a Komfort-class seat or a Nattog sleeper cabin turns the long stretches between stops into part of the enjoyment rather than something to endure. The fjords, the mountains and the changing light are all part of the adventure, not just scenery outside the window. Norway's rail network is smaller than many European countries', but it's internationally noted for scenic beauty rather than speed — and that trade-off is exactly the point.
