The coast of Norway is fringed with jagged fjords cut into the shoreline by glaciers eons ago. One of the most spectacular inlets is the mighty Geirangerfjord, a popular cruising destination and, along with the nearby Nærøyfjord, a UNESCO World Heritage Site. When Norway’s glaciers retreated they left deep valleys in their wake that filled with seawater, in the case of the Geirangerfjord to a depth of nearly 500 meters (1,640 feet). Above the surface, the fjord’s sheer rock walls shoot straight up three times as far. You'll want to wake up early to catch the exhilarating views during the nine-mile cruise up the Geirangerfjord to the tiny village of Geiranger; your ship will likely make this trip in early morning to give you a full day in port. If you’ve sprung for a balcony cabin, you won’t regret it. Otherwise, head for the open decks to soak up the stunning scenery and the crisp, fresh Norwegian air as the ship moves up the calm, glasslike channel.
