This is the section to read if you are still deciding where to go. Each region offers a genuinely different experience, and none is simply a "harder" or "easier" version of another.
Jotunheimen
Hiking in Jotunheimen National Park puts you in the middle of Norway's highest terrain. The "Home of the Giants" holds the two tallest peaks on the Scandinavian mainland, Galdhøpiggen and Glittertind, and the walking reflects that: glacially carved valleys, ridgelines above luminous lakes, and a scale that dwarfs most things in Western Europe. The classic multi-day routes link DNT huts across varied terrain, combining high passes with valley descents and, on some stages, views down to Lake Gjende below. Jotunheimen suits walkers who want a genuine high-mountain feel: the terrain is serious, weather moves fast, and the rewards are commensurately large. It does not suit anyone looking for gentle gradients or forest walking.
Rondane
Rondane is Norway's oldest national park and, by Jotunheimen standards, a gentler one. The terrain is drier, the plateaux wider, and the distances between huts more forgiving. Wild reindeer are a real presence, not a scenic promise, and the sense of open Scandinavian wilderness is hard to match anywhere else in southern Norway. Rondane suits walkers doing their first multi-day trek in Scandinavia, or anyone who prefers the feeling of space over the drama of altitude. What it does not offer is the glacier scenery or peak-to-peak drama of Jotunheimen.
Trollheimen
Trollheimen sits between Jotunheimen and the Trondheim coast and has a different character from both: greener, more wooded on the lower sections, with a mix of river valleys and open summit country in the same loop. The region's relative obscurity among international visitors is part of its appeal. Trails are well-maintained, the DNT huts are welcoming, and the weather window is often slightly more flexible than on the high plateau. Trollheimen suits walkers who want variety within a single route — a day in birch forest followed by a day on open ridges — and those who prefer a loop format.
Aurlandsdalen
Aurlandsdalen is where hiking in the Norwegian fjords becomes a multi-day journey in its own right. The valley is sometimes called Norway's Grand Canyon: a long descent from high mountain plateau to the fjord, following rivers past waterfalls, remote farms and gorge sections that close the sky above you. Fjord Norway hiking at this scale feels like genuine travel through a changing landscape, not a circular walk. The route ends at sea level in the fjord country, which gives it a narrative logic that point-to-point walkers love. The walking is less technically demanding than Jotunheimen but longer in terms of cumulative descent. It does not suit those looking for high ridgelines or summit views.
Lofoten
Hiking in Lofoten is unlike anything else in Norway. The islands sit well above the Arctic Circle, and the mountains rise almost directly from white-sand beaches and the sea. Peaks are shorter in absolute terms than Jotunheimen but feel dramatic out of all proportion to their height, because the contrast between vertical rock, blue water and fishing-village harbours below is immediate and intense. Lofoten is covered here as a destination guide. Bookatrekking currently runs multi-day treks in Jotunheimen, Rondane, Trollheimen and Aurlandsdalen; for Lofoten, the sections below on day walks and famous trails will give you the practical picture.
