Ever more amazing vistas seem to open daily on this cruise dedicated to pepping up your batteries. Plate-glass waters reflect forested slopes rising straight for the skies and distant summits clad in unseasonable snow. Stepping ashore in Ulvik, it's a short way to Osafjord that cuts a cleft 984 ft deep through the scenery. We'll call in Olden, a chance to walk to the foot of the vast Briksdal Glacier, and wind our way up the Flam Railway. Bergen's ancient wharves and Oslo's curious Vigeland sculptures celebrate ancient and modern Norse motifs.
