The true Norwegian cruise line, Hurtigruten has boats that constantly ply the fjords and linger under Northern Lights, venturing as far afield as Greenland and Antarctica. But one of the biggest adventures you can take on one of these very comfortable if no-frills ships is a summer trip around the largest island in Norway's Svalbard archipelago. The circumnavigation of Spitsbergen, allows for cruisers to visit fishing villages and outposts between polar bear, whale and walrus sightings. The midnight sun allows for round-the-clock wildlife viewing, but the fresh seafood might still be the biggest perk of the trip.
