Punn Sanden Beach is the kind of Lofoten beach that feels earned: pale sand, cold water, steep land, and a walk that reminds you this is the North Atlantic, not a resort coast. On Vaeroy, that combination is the attraction.
Go for scenery, photography, and the feeling of space rather than swimming. Weather changes quickly, so carry layers and be ready to turn back if wind or visibility makes the walk unpleasant.
