These Cold-climate Luxury Cruises Will Make You Forget About the Caribbean

“In Search of the Northern Lights,” a new itinerary from Viking, debuts in January; it is perfectly timed to the winter season, which offers the best chance of seeing the Aurora Borealis. On this 13-day voyage leaving from London, you will experience beautiful Norwegian ports such as Stavangar, Bodø, and Tromsø. Beyond witnessing the lights, activities include glacier treks, dog-sledding, and visits with the Sami, the indigenous people of Lapland. (From $4,999 per person.)
