Geiranger

Okay, this entry is not a beach, but that's the point. Fjords, particularly iconic Norwegian fjords like Geirangerfjord, are not good places to find beaches. The steep rocky cliffs plunge directly into deep water, leaving little real estate on which beaches can form. The bedrock may have yielded sediment while glaciated, but that material was all transported far away -- any that was left behind is probably sitting at the bottom of the fjord.
