Norway's draw is the coastline: fjords cut deep inland, and the classic routes combine train, boat and road to reach them. Oslo is the entry point for most trips, Bergen the western hub near the largest fjords, and the Arctic north a separate journey for midnight sun or northern lights.
The guides here cover Oslo and Norway overall. Summer opens mountain roads and ferry schedules that shrink or vanish in winter, so fjord itineraries are effectively seasonal. Costs are high, particularly for food and transport, and booking coastal ferries ahead matters in July and August. Weather in the fjords is wetter than the photographs suggest — Bergen in particular is one of Europe's rainiest cities.
