UNESCO says:
Situated in southwestern Norway, northeast of Bergen, Geirangerfjord and Nærøyfjord, set 120km from one another, are part of the west Norwegian fjord landscape, which stretches from Stavanger in the south to Andalsnes, 500km to the northeast. The two fjords, among the world’s longest and deepest, are considered as archetypical fjord landscapes and among the most scenically outstanding anywhere. Their exceptional natural beauty is derived from their narrow and steep-sided crystalline rock walls that rise up to 1,400m from the Norwegian Sea and extend 500m below sea level. The sheer walls of the fjords have numerous waterfalls while free flowing rivers cross their deciduous and coniferous forests to glacial lakes, glaciers and rugged mountains. The landscape features a range of supporting natural phenomena, both terrestrial and marine such as submarine moraines and marine mammals.
