Norway submitted Nærøyfjord and Geirangerfjord for UNESCO World Heritage designation in 2005; the committee recognised them as textbook examples of fjord landscape formation, shaped by repeated Quaternary glaciations that carved valleys 1,308 metres below sea level.
Nærøyfjord narrows to 250 metres at its tightest passage, flanked by vertical rock faces rising 1,400 metres — a depth-to-width ratio unmatched in accessible Scandinavian waterways. The fjord extends 17 kilometres inland from Gudvangen to the mouth of Aurlandsfjord, itself an eastern arm of Sognefjord, the longest and deepest fjord system in Norway at 204 kilometres and 1,308 metres maximum depth.
Flåm sits at the innermost shore of Aurlandsfjord, a village of 350 permanent residents that serves 450,000 cruise passengers annually. The settlement gained strategic importance in 1940 when the Flåm Railway opened, connecting fjord level to the Bergen-Oslo mainline at Myrdal, 20 kilometres distant and 863 metres higher. Engineers spent seventeen years carving the route through Flåmsdalen valley; eighteen of the line's twenty tunnels were hand-bored. Trains descend at a 5.5 percent gradient — the steepest standard-gauge adhesion railway in Europe — passing through Kjosfossen waterfall's 93-metre plunge midway.
The Bergen fjord cruise to Flåm route departs Zachariasbryggen at Bergen harbour, threading through the Mostraumen strait where tidal currents reach four knots during spring flood. Vessels enter Sognefjord at Hjeltefjorden junction, then turn east past Aurland village. Most operators include a stop at Stegastein viewpoint, a 30-metre cantilevered platform 650 metres above Aurlandsfjord, completed in 2006 by architect Todd Saunders and structural engineer Arne Eggen. Return journeys typically combine southbound rail descent from Myrdal with coach transfer segments, completing a 12-hour loop.
Flåm's visitor centre, rebuilt in 2018, houses the Norwegian Wild Salmon Centre and a permanent exhibition on fjord geomorphology. The railway museum occupies the original 1940 station building, preserving manual signal equipment and rotary snowploughs used until electrification in 1998. Five daily Flåm Railway departures run year-round; winter services reduce to three.
